The conversion of 1 chain equals 20.1168 metres. This means that if you have a measurement of 1 chain, it is equivalent to approximately 20.12 metres.
A chain is a unit of length traditionally used in land surveying, and it measures exactly 66 feet or 22 yards. Since a metre is a metric unit of length, converting chains to metres involves knowing how many metres are in a foot and applying the conversion factor accordingly. Specifically, 1 foot equals 0.3048 metres. Therefore, multiplying 66 feet by 0.3048 gives the length of one chain in metres.
Conversion Result
1 chain is equal to 20.1168 metres.

Conversion Formula
The formula to convert chains to metres multiplies the number of chains by 20.1168 because 1 chain equals 66 feet, and each foot is 0.3048 metres. So, (chains) × 66 feet × 0.3048 meters/foot = chains × 20.1168 meters. For example, converting 2 chains: 2 × 20.1168 = 40.2336 metres.
Conversion Example
- Converting 3 chains:
- Multiply 3 by 20.1168.
- 3 × 20.1168 = 60.3504 metres.
- This shows 3 chains equal about 60.35 metres.
- Converting 0.5 chains:
- Multiply 0.5 by 20.1168.
- 0.5 × 20.1168 = 10.0584 metres.
- So, half a chain is around 10.06 metres.
- Converting 10 chains:
- Multiply 10 by 20.1168.
- 10 × 20.1168 = 201.16 metres.
- Thus, 10 chains equal approximately 201.16 metres.

Conversion Definitions
Chain
A chain is a land measurement unit used in surveying, comprising 66 feet or 22 yards, traditionally employed to measure land plots and distances, especially in the United States and UK, now largely replaced by metric units in many applications.
Metres
Metres are the base unit of length in the metric system, defined as the distance light travels in vacuum in 1/299,792,458 seconds, used globally for scientific, engineering, and everyday measurement purposes.
Conversion FAQs
What is the historical origin of the chain measurement?
The chain originated from medieval land measurement practices, designed for ease of use in planning land plots. It was standardized in the 16th century by surveyors to simplify calculations and land division, especially in the British Isles.
Why is the metre considered the standard unit of length worldwide?
The metre was adopted globally in the 19th century as part of the metric system, based on universal constants like the speed of light, providing a consistent and precise standard for scientific and everyday measurements across countries.
How accurate is the conversion from chain to metres?
The conversion is based on exact definitions: 1 chain is exactly 66 feet, and 1 foot equals 0.3048 metres, making the conversion precise. Minor rounding in decimal places may occur, but overall, the measurement is highly accurate.
