What is a Roman Mile and a Link (Gunter's)?
The Roman Mile (mille passus, meaning "thousand paces"; symbol m.p.) was the standard Roman unit for measuring longer distances.
It was defined as 1,000 Roman paces (passus).
Since one passus (a double step) was equal to 5 Roman feet (pes), the Roman mile was equivalent to:
- 1,000 paces (passus)
- 5,000 Roman feet (pedes)
The exact length varied slightly depending on the precise definition of the Roman foot used, but it is typically estimated as:
- Approximately 1,480 meters (m)
- Approximately 1.48 kilometers (km)
- Approximately 0.919 statute miles (mi)
- Approximately 4,856 feet (ft) (using a common estimate for the Roman foot)
The Link, specifically Gunter's Link (symbol li), is a unit of length historically used in surveying, particularly within the imperial and U.S. customary systems. It is defined as exactly 1/100th of a Gunter's chain.
One Gunter's link is equivalent to:
- 0.01 Gunter's chains
- 7.92 inches (in)
- 0.66 feet (ft) (exactly 2/3 of a foot)
- 0.22 yards (yd)
- 0.04 rods (also called poles or perches)
- 0.201168 meters (m) (exactly)
- 20.1168 centimeters (cm)
A Gunter's chain itself measures 66 feet, 22 yards, 4 rods, or 20.1168 meters.
Note: The Roman Mile is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Link (Gunter's) belongs to the imperial/US customary system.
History of the Roman Mile and Link (Gunter's)
The Roman mile was established during the Roman Republic and Empire and was used extensively throughout Roman territories for measuring roads, distances between cities, and military movements. Roman roads were famously marked with milestones (miliarium) indicating the distance in Roman miles, often back to the Milliarium Aureum (Golden Milestone) in the Forum Romanum.
The Roman mile significantly influenced the development of the mile unit in other countries, including the English statute mile, although the lengths eventually diverged.
The link, as part of Gunter's chain, was devised by the English clergyman and mathematician Edmund Gunter around 1620. He introduced a measuring chain that was 66 feet long and divided into 100 links. This system was revolutionary for surveyors because its decimal nature (100 links per chain) simplified calculations, especially for area. Land area could be easily calculated in square chains and then converted to acres, as 10 square chains equal exactly 1 acre. Gunter's chain and its links became the standard tools for land surveying in England and later throughout the British Empire and the United States for centuries.
Common Uses for Roman miles and links
Explore the typical applications for both Roman Mile (imperial/US) and Link (Gunter's) (imperial/US) to understand their common contexts.
Common Uses for Roman miles
- Historical Measurement: Used ubiquitously in the Roman Empire for all land distances.
- Historical Texts: Essential for understanding distances mentioned in Roman literature, historical accounts, and geographical works.
- Archaeology: Used to interpret Roman road networks, milestone placements, and site layouts.
Common Uses for links
The Gunter's link is now largely obsolete but was historically significant:
- Land Surveying: It was the fundamental unit for measuring property boundaries and land parcels in English-speaking countries for over 300 years.
- Cartography: Used in creating maps and plats based on surveys.
- Land Records: Measurements in links (and chains) frequently appear in older property deeds, historical surveys, and legal descriptions of land. Understanding the link is crucial for interpreting these documents.
- Agriculture: The system was tied to the definition of the acre, a common unit of land area.
Its use declined dramatically with the adoption of the metric system and the advent of more precise surveying technologies like steel tapes, theodolites, Electronic Distance Measurement (EDM), and GPS.
Frequently Asked Questions
Questions About Roman Mile (m.p.)
How long was a Roman Mile compared to a modern mile?
A Roman mile (approx. 1480 m) was shorter than the modern international statute mile (1609.344 m). A Roman mile is about 92% the length of a modern statute mile.
What does 'mille passus' mean?
It's Latin for "a thousand paces". Mille means thousand, and passus refers to the Roman pace (a double step of 5 Roman feet).
How many feet were in a Roman Mile?
There were 5,000 Roman feet (pedes) in one Roman mile.
Is the Roman Mile still used?
No, the Roman mile is obsolete and not used for any modern measurements. It is purely a historical unit. Modern distances are measured in kilometers or statute miles.
About Link (Gunter's) (li)
How long is a Gunter's Link?
One Gunter's Link is equal to:
- 7.92 inches
- 0.66 feet (2/3 ft)
- 0.201168 meters
- 20.1168 centimeters
How many links are in a Gunter's chain?
There are exactly 100 links in one Gunter's chain.
How long is a Gunter's Chain?
One Gunter's chain is equal to:
- 100 links
- 66 feet
- 22 yards
- 4 rods (or poles, perches)
- 1/10th of a furlong
- 1/80th of a statute mile
- 20.1168 meters
How does the link relate to the acre?
The link is directly related to the acre through the Gunter's chain. An acre is defined as 10 square chains. Since 1 chain = 100 links:
- 1 acre = 10 × (100 links)² = 10 × 10,000 square links = 100,000 square links. This decimal relationship greatly simplified area calculations for surveyors using the chain.
Is the link an SI unit?
No, the Gunter's link is not an SI unit. It is part of the traditional imperial and U.S. customary systems. The corresponding SI unit for length is the meter (m).
Is the Gunter's link still used today?
No, the Gunter's link is rarely used in modern surveying practice. Its primary relevance today is in historical contexts, particularly when interpreting old land deeds, surveys, and maps created using Gunter's system. Modern surveying relies on meters or feet, measured with advanced electronic equipment.
Why was it called a 'link'?
It was called a 'link' because Gunter's chain was literally constructed from 100 physical metal links connected by rings. Each link served as a unit of measurement.
