The Eighth of a Mile
The furlong is defined as exactly 1/8 of a statute mile.
Precise equivalents:
- 220 yards (1/8 × 1,760 yards)
- 660 feet (220 yards × 3 feet/yard)
- 40 rods (traditional surveying unit; 1 rod = 16.5 feet)
- 10 chains (1 chain = 66 feet = 4 rods)
- 201.168 meters (exactly, using 1 yard = 0.9144 m)
Old English Etymology
"Furlang" = "furrow-long"
- Furh (Old English) = furrow (a trench cut by a plow)
- Lang (Old English) = long
Agricultural origin: In medieval open-field farming, peasants plowed long, narrow strips. The furlong represented the standard length of these strips—the distance a team of oxen could pull a heavy plow before needing to rest and turn around.
Why this specific distance?
- Oxen stamina: Approximately 220 yards before fatigue
- Practical turn-around: Long enough to be efficient, short enough to manage
- Acre relationship: 1 furlong × 1 chain (66 ft) = 1 acre (historical definition)
The Chain-Furlong-Mile System
Edmund Gunter's surveyor's chain (1620):
- 1 chain = 66 feet = 4 rods = 100 links
- 10 chains = 1 furlong
- 80 chains = 1 mile
Why 66 feet? Gunter designed the chain so that:
- 10 square chains = 1 acre (exactly)
- Easy conversion between area and distance
- Practical length for field surveying (two surveyors could carry it)
This system dominated English-speaking land surveys for 300+ years.
A micrometer is a unit of length in the metric system equal to one millionth (1/1,000,000) of a meter. The term derives from the Greek "mikros" (small) and "metron" (measure). It is abbreviated as μm, where μ (mu) is the Greek letter representing the prefix "micro-."
Note on terminology: While "micron" was widely used from 1879 to 1967, it was officially deprecated by the International System of Units (SI) in favor of "micrometer" to maintain consistent naming conventions. However, "micron" remains common in some industries, particularly semiconductor manufacturing and filtration.
The micrometer sits between the millimeter and nanometer on the metric scale:
- 1 meter = 1,000,000 micrometers
- 1 millimeter = 1,000 micrometers
- 1 micrometer = 1,000 nanometers
This scale makes micrometers perfect for measuring objects visible under optical microscopes but invisible to the naked eye.

Note: The Furlong is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Micrometer belongs to the metric (SI) system.
History of the Furlong and Micrometer
Anglo-Saxon Origins (5th-11th Centuries)
Open-field strip farming: Medieval English villages practiced communal agriculture, with fields divided into long, narrow strips assigned to different families.
Strip dimensions:
- Length: 1 furlong (~220 yards)
- Width: 1 chain (~22 yards, later standardized to 1 chain = 66 feet / 4 rods)
- Area: Approximately 1 acre
Plowing practice: Farmers plowed the length of the strip (1 furlong), then turned the ox team at the headland (the unplowed area at each end). The furlong emerged as the natural unit for this plowing distance.
Norman and Plantagenet Standardization (11th-14th Centuries)
Domesday Book (1086): William the Conqueror's land survey used furlongs and acres to catalog English landholdings, cementing these units in law.
Statute of 1305 (Edward I): Formalized the furlong as:
- 40 rods (1 rod = 16.5 feet = 5.5 yards)
- 1/8 mile
- Standard for all land measurement in England
Acre definition: Legally defined as 1 furlong × 4 rods (1 furlong × 66 feet), creating the enduring acre-furlong relationship.
Edmund Gunter and the Surveyor's Chain (1620)
Revolutionary tool: English mathematician Edmund Gunter invented the surveyor's chain, a 66-foot measuring chain with 100 links.
Advantages:
- Durability: Metal chain resisted wear better than ropes
- Accuracy: Standardized links prevented stretching errors
- Calculation ease: 100 links made decimal-like subdivision simple
- Furlong integration: 10 chains = 1 furlong (exact)
Global spread: Gunter's chain became the standard surveying tool throughout the British Empire, spreading the furlong to:
- North America (colonial land surveys)
- Australia (1788 onwards)
- India (British Raj)
- Africa (colonial territories)
Horse Racing Adoption (18th Century)
The Jockey Club (founded 1750): British horse racing's governing body standardized race distances in furlongs and miles.
Common race distances established:
- 5 furlongs: Sprint races
- 1 mile (8 furlongs): Classic middle distance
- 1.5 miles (12 furlongs): St. Leger Stakes (established 1776)
- 2.5 miles (20 furlongs): Royal Ascot Gold Cup
Why furlongs?
- Traditional British measurement
- Convenient divisions of the mile
- Allowed precise race distance specifications
- Established in racecourse infrastructure (distance poles)
American Horse Racing (19th Century)
Kentucky Derby (1875): Established at 1.5 miles (12 furlongs), later shortened to 1.25 miles (10 furlongs) in 1896. The furlong became America's standard racing measurement.
Belmont Stakes (1867): Originally 1.625 miles, standardized to 1.5 miles (12 furlongs)—the "Test of the Champion."
Preakness Stakes (1873): Run at 9.5 furlongs (1.1875 miles).
All three Triple Crown races use furlong-based distances.
Metrication and Decline (20th Century)
UK Weights and Measures Act (1985): Officially transitioned Britain to metric system for most purposes. The furlong became obsolete for:
- Road distances (now kilometers)
- Land surveying (now meters)
- General measurement (meters standard)
Exception: Horse racing Racing authorities worldwide retained furlongs, grandfathered as a traditional sporting measure.
Modern Persistence (21st Century)
Countries still using furlongs in horse racing:
- United Kingdom: All thoroughbred racing
- Ireland: All thoroughbred racing
- United States: All thoroughbred and quarter horse racing
- Canada: Thoroughbred racing
- Australia: Some racing uses furlongs alongside meters
- Myanmar (Burma): Road signs and general distance measurement
Global standard: Despite metrication, international horse racing maintains furlong terminology for consistency with historical records and tradition.
The concept of the micrometer emerged alongside the development of precision microscopy in the 17th and 18th centuries. As scientists like Robert Hooke and Antonie van Leeuwenhoek observed cells and microorganisms for the first time, they needed standardized ways to describe these microscopic dimensions.
The term "micron" (μ) was officially adopted at the First International Electrical Congress in Paris in 1879 as a convenient shorthand for one millionth of a meter. This simplified notation became widely used in scientific literature, particularly in biology, materials science, and optics.
In 1960, the International System of Units (SI) was established to create consistent naming conventions across all units. By 1967-1968, the SI officially deprecated "micron" in favor of "micrometer" to align with the systematic naming structure where prefixes like "micro-," "nano-," and "kilo-" are clearly indicated.
Despite this official change, the term "micron" persists in several industries:
- Semiconductor manufacturing: Process nodes like "5-micron technology"
- Filtration systems: "10-micron water filter"
- Materials science: Particle size specifications
- Aerospace: Surface finish requirements
The symbol μm is universally recognized in scientific and technical documentation, combining the Greek letter μ (representing the micro- prefix meaning 10⁻⁶) with m for meter.
Today, micrometers are fundamental to numerous high-precision fields, from medical diagnostics and semiconductor fabrication to quality control and environmental monitoring.
Common Uses and Applications: furlongs vs micrometers
Explore the typical applications for both Furlong (imperial/US) and Micrometer (metric) to understand their common contexts.
Common Uses for furlongs
1. Thoroughbred Horse Racing
Race distance specification: Nearly all English-language racing nations specify race lengths in furlongs.
Examples:
- "A 6-furlong sprint on turf"
- "The colt won at distances from 8 to 12 furlongs"
- "She specializes in 5-furlong races"
Racecourse markers: Distance poles along the track show remaining furlongs to the finish (e.g., "4F" pole = 4 furlongs to go).
2. Breeding and Training
Horse pedigrees: Thoroughbred bloodlines are analyzed by optimal racing distances measured in furlongs.
Example: "This stallion's progeny excel at 8-10 furlongs, inheriting his stamina."
Training distances: Trainers describe workout distances in furlongs: "We gave him a strong 6-furlong breeze this morning."
3. Myanmar (Burma)
Road distances: Myanmar road signs often show distances in furlongs and miles rather than kilometers.
Example: "Yangon 12 furlongs" (1.5 miles ahead)
Why? British colonial legacy; Myanmar has resisted full metrication.
4. Historical Documents
Land deeds: Property descriptions in English-speaking countries often reference furlongs:
"Beginning at the oak tree, thence north 3 furlongs, thence east 2 furlongs..."
Literary references: Classic literature mentions furlongs for travel distances.
When to Use micrometers
1. Microscopy and Biology
Micrometers are the standard unit for measuring cells, bacteria, and other microorganisms under optical microscopes. Lab technicians and researchers use calibrated eyepiece scales marked in micrometers to measure biological specimens. Cell biology, microbiology, and histology all depend on micrometer measurements for specimen identification and analysis.
2. Semiconductor Manufacturing
The semiconductor industry uses micrometers (often called "microns") to specify process node sizes, though modern chips have moved to nanometer scales. Wafer thickness (typically 725 μm for 300mm wafers), photoresist layers, and older chip features are measured in micrometers. Quality control requires precise measurements to ensure manufacturing tolerances.
3. Precision Engineering
Manufacturing engineers specify tolerances in micrometers for high-precision components. CNC machining, grinding, and polishing operations achieve accuracies of ±1-10 μm. Measuring instruments like micrometers (the tool) can measure to 0.001 mm = 1 μm precision. Critical aerospace, medical device, and automotive components require micrometer-level quality control.
4. Fiber Optics and Telecommunications
Fiber optic cables have core diameters measured in micrometers: single-mode fibers typically use 8-10 μm cores, while multi-mode fibers range from 50-62.5 μm. The precise core diameter determines light transmission characteristics, bandwidth, and distance capabilities. Telecom technicians reference these specifications when installing and troubleshooting fiber networks.
5. Filtration and Air Quality
Filter manufacturers rate products by the size of particles they capture, measured in micrometers. HEPA filters capture 99.97% of particles ≥0.3 μm. Water filters, air purifiers, and industrial filtration systems all use micrometer ratings. Environmental agencies track PM2.5 (particulate matter <2.5 μm) and PM10 pollution, which pose respiratory health risks.
6. Medical Diagnostics
Medical laboratories measure blood cells in micrometers: red blood cells average 6-8 μm, while variations may indicate conditions like anemia. Pathologists examine tissue samples and tumor margins at micrometer scale. Medical device manufacturing (catheters, needles, implants) requires micrometer-precision specifications for safety and efficacy.
Convert Medical Measurements →
7. Surface Finish and Coatings
Surface roughness is measured in micrometers using parameters like Ra (average roughness). A mirror finish might be <0.1 μm Ra, while machined surfaces range from 0.8-25 μm Ra. Coating thickness—paint, anodizing, plating—is specified in micrometers to ensure corrosion protection and aesthetic quality.
Additional Unit Information
About Furlong (fur)
How many furlongs are in a mile?
Exactly 8 furlongs = 1 statute mile.
This is the defining relationship:
- 1 furlong = 1/8 mile = 0.125 miles
- 1 mile = 8 furlongs = 1,760 yards = 5,280 feet
How many yards/feet/meters are in a furlong?
1 furlong equals:
- 220 yards (exactly)
- 660 feet (220 × 3)
- 201.168 meters (exactly, using international yard definition)
Derivation: 1 mile = 1,760 yards 1/8 mile = 1,760 ÷ 8 = 220 yards
Where is the furlong used most often today?
Primary use: Horse racing
Countries:
- United Kingdom: All thoroughbred flat and jump racing
- Ireland: All racing
- United States: Thoroughbred and quarter horse racing standard
- Canada: Thoroughbred racing
- Australia: Some racing (alongside meters)
Secondary use:
- Myanmar (Burma): Road distances, general measurement
Historical references:
- Land deeds and property surveys (historical documents)
- Classic literature
Is the furlong an SI unit?
No, the furlong is not part of the International System of Units (SI).
It belongs to the imperial and U.S. customary measurement systems. The SI unit for length is the meter.
Legal status:
- UK: Permitted for specific uses (horse racing, historical contexts)
- US: Legal, but not commonly used outside racing
- Myanmar: Customary unit
Why is it called a furlong?
Etymology: Old English "furlang" = "furrow-long"
Origin:
- Furh = furrow (trench cut by plow)
- Lang = long
Agricultural meaning: The distance a team of oxen could plow a furrow before needing to rest—approximately 220 yards.
Historical context: Medieval open-field strip farming created long, narrow fields. The furlong defined the standard strip length, while the chain (66 feet) defined the width, producing a 1-acre plot.
Why does horse racing still use furlongs?
Historical tradition: British horse racing standardized on furlongs in the 18th century (Jockey Club, 1750). Racing infrastructure, records, and terminology built around furlongs over 270+ years.
Practical advantages:
- Convenient divisions: 1 mile divides evenly into 8 furlongs, creating simple race distances (5, 6, 7, 8, 10, 12 furlongs)
- Global consistency: Using furlongs allows comparison across centuries of racing records
- Infrastructure: Historic racecourses designed with furlong markers and measurements
Resistance to change: Metrication efforts in the 1970s-1990s met strong resistance from racing traditionalists. The sport successfully lobbied to preserve furlongs as a cultural heritage measure.
How long is the Kentucky Derby in furlongs?
10 furlongs = 1.25 miles = 2,012 meters
History:
- 1875-1895: 1.5 miles (12 furlongs)
- 1896-present: 1.25 miles (10 furlongs)
The distance was shortened to 10 furlongs in 1896 and has remained unchanged since, becoming known as "The most exciting two minutes in sports" (approximate finishing time for winners).
What's the difference between a furlong and a chain?
Both are imperial length units, but different sizes:
Furlong:
- 220 yards = 660 feet = 201.168 m
- Used for longer distances (racing, field lengths)
Chain (Gunter's chain):
- 66 feet = 22 yards = 20.1168 m
- 1 furlong = 10 chains
- Used for detailed land surveying
Historical relationship: Edmund Gunter designed the chain so that 10 chains = 1 furlong, creating an integrated surveying system.
Can I convert racecourse distances from furlongs to meters?
Yes, multiply by 201.168.
Common conversions:
- 5 furlongs × 201.168 = 1,006 m (~1 km)
- 6 furlongs × 201.168 = 1,207 m
- 8 furlongs × 201.168 = 1,609 m (~1 mile)
- 10 furlongs × 201.168 = 2,012 m
- 12 furlongs × 201.168 = 2,414 m
Note: Many international racing jurisdictions use round meter distances (1200m, 1600m, 2000m) rather than exact furlong equivalents.
Is a furlong longer than a kilometer?
No, a furlong is shorter than a kilometer.
Comparison:
- 1 furlong = 201.168 meters = 0.201 km
- 1 kilometer = 1,000 meters ≈ 4.97 furlongs (~5 furlongs)
Memory aid: 5 furlongs ≈ 1 kilometer
About Micrometer (μm)
Is a micrometer the same as a micron?
Yes, micrometer and micron refer to the same unit: one millionth of a meter (1×10⁻⁶ m or 1 μm). The term "micron" (symbol: μ) was officially used from 1879 to 1967 but was deprecated by the International System of Units (SI) in favor of "micrometer" to maintain consistent naming conventions.
Despite being officially deprecated, "micron" remains common in several industries:
- Semiconductor manufacturing ("5-micron process")
- Filtration ("10-micron filter")
- Materials science (particle size specifications)
In scientific and technical writing, "micrometer" (μm) is the preferred term, but both are universally understood.
How many micrometers are in a millimeter?
There are 1,000 micrometers (μm) in 1 millimeter (mm). This makes sense when you consider the metric prefixes:
- "Milli-" means one thousandth (1/1,000)
- "Micro-" means one millionth (1/1,000,000)
Since a micrometer is 1,000 times smaller than a millimeter, dividing 1 mm into 1,000 equal parts gives you 1 μm per part.
Examples:
- 0.5 mm = 500 μm
- 0.1 mm = 100 μm
- 0.075 mm = 75 μm (typical human hair)
Convert Millimeters to Micrometers →
What are some examples of things measured in micrometers?
Biological:
- Bacteria: 1-10 μm (E. coli ≈ 2 μm)
- Red blood cells: 6-8 μm
- Human hair diameter: 50-100 μm
- Pollen grains: 10-100 μm
Technology:
- Fiber optic core: 8-62.5 μm (depending on type)
- Semiconductor features: 0.01-10 μm (older processes)
- Surface roughness: 0.1-25 μm (machining)
Materials:
- Paint thickness: 25-100 μm
- Plastic wrap: 10-15 μm
- Paper thickness: 70-100 μm
Essentially, anything visible under an optical microscope but invisible to the naked eye is measured in micrometers.
How do I convert micrometers to inches?
To convert micrometers to inches, multiply by 0.00003937 (or divide by 25,400).
Formula: inches = micrometers × 0.00003937
Examples:
- 100 μm × 0.00003937 = 0.003937 inches (≈ 0.004")
- 1,000 μm × 0.00003937 = 0.03937 inches (≈ 0.04")
- 2,540 μm × 0.00003937 = 0.1 inches
For context, 1 inch = 25,400 μm (or 25.4 mm), so micrometers are extremely small when expressed in imperial units.
Convert Micrometers to Inches →
Can the human eye see micrometers?
The human eye's resolution limit is approximately 50-100 micrometers under ideal conditions. This means:
Barely visible (with perfect vision):
- Thick human hair: 100 μm
- Fine sand grains: 100-500 μm
- Large dust particles: 100+ μm
Invisible without magnification:
- Bacteria: 1-10 μm
- Red blood cells: 6-8 μm
- Fine dust: <50 μm
- Most microorganisms: <50 μm
To see objects smaller than ~50 μm, you need a microscope. Optical microscopes can resolve features down to about 0.2 μm (200 nm), while electron microscopes can see structures at the nanometer scale.
What is the difference between micrometer and nanometer?
A micrometer (μm) equals one millionth of a meter (10⁻⁶ m), while a nanometer (nm) equals one billionth of a meter (10⁻⁹ m). This means 1 micrometer = 1,000 nanometers.
Scale comparison:
- Micrometer scale: bacteria, cells, human hair (1-100 μm)
- Nanometer scale: viruses, molecules, atoms (1-100 nm)
Examples:
- Red blood cell: 7,000 nm = 7 μm
- Coronavirus particle: 100 nm = 0.1 μm
- DNA helix width: 2 nm = 0.002 μm
- Silicon atom: 0.2 nm = 0.0002 μm
Optical microscopes work at the micrometer scale, while electron microscopes are needed for nanometer-scale imaging.

How accurate are micrometer measuring tools?
A micrometer (the measuring instrument, also called a "mike") typically measures with an accuracy of ±0.001 mm (±1 μm) for standard models, and ±0.0001 mm (±0.1 μm) for digital precision models.
Types and accuracy:
- Standard mechanical: ±0.001 mm (±1 μm)
- Vernier micrometer: ±0.001 mm (±1 μm)
- Digital micrometer: ±0.0005-0.001 mm (±0.5-1 μm)
- High-precision digital: ±0.0001 mm (±0.1 μm)
Accuracy depends on:
- Tool quality and calibration
- Temperature (thermal expansion affects readings)
- Operator technique (proper force and reading)
- Workpiece surface condition
For even higher precision, coordinate measuring machines (CMMs) and optical comparators can achieve sub-micrometer accuracy in controlled environments.
Why was "micron" deprecated?
The International System of Units (SI) deprecated "micron" in 1967-1968 to maintain consistent naming conventions across all metric units. The SI system uses standard prefixes (micro-, nano-, kilo-, etc.) combined with base units (meter, gram, second) to create derived units.
Reasons for change:
- Consistency: "Micrometer" follows the pattern of millimeter, nanometer, kilometer
- Clarity: Combines "micro-" (10⁻⁶) with "meter" to clearly indicate the scale
- International standardization: Reduces confusion in scientific communication
- Symbol standardization: μm is unambiguous, while μ alone could be confused with other uses
Why "micron" persists:
- Shorter and easier to say ("micron" vs "micrometer")
- Decades of industry usage before 1967
- Well-established in semiconductor, filtration, and materials industries
- No confusion in context (everyone knows what "10-micron filter" means)
In formal scientific writing, use "micrometer (μm)" for SI compliance.
What equipment measures in micrometers?
Precision measuring instruments:
- Micrometer caliper (the tool): Measures dimensions to ±1 μm accuracy
- Dial indicator: Measures displacement to ±1-5 μm
- Coordinate Measuring Machine (CMM): Sub-micrometer accuracy
- Optical comparator: Projects magnified image for micrometer-scale inspection
- Laser interferometer: Measures to nanometer/sub-micrometer accuracy
Microscopy equipment:
- Optical microscope: With calibrated eyepiece scales (reticles) marked in micrometers
- Confocal microscope: 3D imaging with micrometer resolution
- Scanning Electron Microscope (SEM): Nanometer resolution but calibrated in micrometers
Surface analysis:
- Surface roughness tester (profilometer): Measures Ra, Rz in micrometers
- Thickness gauge: Coating thickness to ±1 μm
- Film thickness measurement: Non-contact optical methods
Quality control:
- Particle size analyzers: Measure suspended particles in micrometers
- Laser diffraction instruments: Characterize powders and emulsions
How is micrometer used in air quality standards?
Air quality standards use micrometers to classify particulate matter (PM) by size, which determines health impacts:
PM10 (Particulate Matter <10 μm):
- Includes dust, pollen, mold
- Can reach lungs but often trapped in nose/throat
- EPA 24-hour standard: 150 μg/m³
PM2.5 (Particulate Matter <2.5 μm):
- Includes combustion particles, smoke, fine dust
- Small enough to enter deep into lungs and bloodstream
- EPA 24-hour standard: 35 μg/m³
- More dangerous than PM10 due to deep lung penetration
Why size matters:
- >10 μm: Trapped in nose and throat
- 2.5-10 μm: Can reach upper respiratory tract and lungs
- <2.5 μm: Can penetrate deep into lungs and enter bloodstream
- <0.1 μm (ultrafine): Can cross into organs and brain
Filter effectiveness:
- HEPA filters: Capture 99.97% of particles ≥0.3 μm
- N95 masks: Filter 95% of particles ≥0.3 μm
- Standard HVAC filters: Typically 3-10 μm particle capture
Understanding micrometer-scale particle sizes is critical for respiratory health, especially for vulnerable populations.
