About Converting Meters to Chains
Meter and Chain both measure length. Meter is most often used for universal scientific and everyday length measurement outside the us.
Formula
chains = meters × 0.049709695379
This factor comes from each unit's defined relationship to the category's base unit: 1 meter equals 1 base unit, and 1 chain equals 20.1168 base units, so dividing one by the other gives the direct meter-to-chain factor of 0.049709695379.
Simple example
1 m × 0.04970969538 = 0.0497096954 ch
1 meter = 0.0497096954 chains.
Real-world example
10 m × 0.04970969538 = 0.4970969538 ch
10 meters = 0.4970969538 chains.

Reverse conversion: Chain to Meter
0.0497096954 ch × 20.1168 = 1 m
0.0497096954 chains = 1 meters.
meters = chains × 20.1168

Understanding the Meter
Meter (m) measures distance. The meter is the SI base unit of length, currently defined via the fixed speed of light. It is classified as a SI base unit.
Where it's used: Standard length unit worldwide except the US
Uses of the Meter today
- Universal scientific and everyday length measurement outside the US
- Construction, engineering, and manufacturing internationally
History of the Meter
Defined during the French Revolutionary metric reforms as one ten-millionth of the distance from the North Pole to the Equator, the meter has been redefined several times for precision — a platinum-iridium bar (1889), a krypton-86 wavelength (1960), and since 1983, the distance light travels in 1/299,792,458 of a second.
Historical origin. Meter was not the invention of a single named person; it developed through the process described above.
Understanding the Chain (ch)
A surveyor's chain is 66 feet.

Frequently asked questions
How many chains are in 1 meter?
1 meter equals 0.0497096954 chains, using the exact defined conversion factor rather than an estimate.
How do I convert meter to chain?
Multiply the meter value by 0.04970969538. The converter above does this instantly to whatever precision you set.
How do I convert chain back to meter?
Use the reverse factor: 1 chain equals 20.1168 meters. You can also use the swap control in the converter above to flip the direction instantly.
What is a meter?
Meter (m) measures distance. The meter is the SI base unit of length, currently defined via the fixed speed of light. It is classified as a SI base unit.
What is a chain?
Chain (ch) is a unit of length.
Is the meter to chain conversion exact?
Yes. Both meter and chain are defined by fixed standards rather than physical artifacts, so the factor of 0.04970969538 used above is exact to as many digits as you choose to display.
Where is the meter still used today?
Standard length unit worldwide except the US
