What is a Furlong and a Micrometer?
The Furlong (symbol fur) is a unit of length in the imperial and U.S. customary systems of measurement. It is defined as exactly one-eighth of a mile (1/8 mi). This is equivalent to 220 yards (yd), 660 feet (ft), or precisely 201.168 meters (m).
A micrometer, also known as a micron, is a unit of length equal to one millionth of a meter (1×10⁻⁶ m).
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
The name "furlong" derives from the Old English words furh (furrow) and lang (long). It originally represented the approximate distance a team of oxen could plow without rest within a typical English open field system. It also related to the traditional size of an acre, which was conceived as an area of land one furlong long and one chain (66 feet) wide. The furlong was standardized as 40 rods (a rod being 5.5 yards) or 10 chains. While historically significant in agriculture and land surveying, its use has greatly diminished with the adoption of metric units and the decline of the imperial system for general measurements.
The term micron was officially accepted between 1879 and 1967 but later deprecated. Micrometer is the current standard term.
Common Uses for furlongs and micrometers
Explore the typical applications for both Furlong (imperial/US) and Micrometer (metric) to understand their common contexts.
Common Uses for furlongs
Although largely obsolete for general use, the furlong persists in specific contexts:
- Horse Racing: Its most prominent modern use is in measuring race distances in countries like the United Kingdom, Ireland, the United States, and Canada. Race lengths are frequently given in furlongs (e.g., a 6-furlong sprint).
- Historical Context: Encountered in historical documents, land deeds, and literature referring to land measurement or travel distances in imperial units.
- Figurative Language: Occasionally used informally or figuratively to denote a distance, though this is rare.
- Myanmar (Burma): The furlong remains in common use in Myanmar as a customary unit alongside the mile.
Common Uses for micrometers
- Measuring microscopic objects (e.g., bacteria, cells)
- Precision engineering tolerances
- Semiconductor manufacturing
Frequently Asked Questions
Questions About Furlong (fur)
How many furlongs are in a mile?
There are exactly 8 furlongs in 1 mile.
How many yards/feet/meters are in a furlong?
One furlong is equal to:
- 220 yards (yd)
- 660 feet (ft)
- 201.168 meters (m) (exactly)
Where is the furlong used most often today?
Its primary modern application is in horse racing in several English-speaking countries (UK, Ireland, USA, Canada), where it is the standard unit for race distances. It also sees some continued customary use in Myanmar.
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 systems. The corresponding SI unit for length is the meter (m).
Why is it called a furlong?
The name comes from Old English furlang, meaning "furrow long," reflecting its origin as the length of a furrow a team of oxen could plow in an acre strip before needing rest.
About Micrometer (μm)
Is a micrometer the same as a micron?
Yes, 'micron' is an older, deprecated name for the micrometer (μm). Both refer to one millionth of a meter.
How many micrometers are in a millimeter?
There are 1,000 micrometers (μm) in 1 millimeter (mm).
What are some examples of things measured in micrometers?
Examples include the diameter of human hair (around 50-100 μm), bacteria (typically 1-10 μm), and the thickness of plastic bags.
