# Chains to Meters (ch to m)

Source: https://www.unitconvertercalculator.com/length/chains-to-meters/

**1 ch = 20.1168 m**

One chain equals exactly 20.1168 meters. This is the most important chain-to-metric conversion, used when translating historical land surveys into the SI standard unit of length. Property descriptions, old maps, and survey records in chains must be converted to meters for modern cadastral and GIS applications.

## Units

### Chain (ch)

Exactly 66 feet or 4 rods (20.1168 m). Invented by Edmund Gunter for land surveying. 80 chains make one mile. Still used in US public land surveys.

### Meter (m)

The base unit of length in the International System of Units (SI). Used worldwide as the standard measure of distance.

## Background

A cricket pitch is exactly 1 chain (20.1168 m). One furlong (10 chains) is 201.168 m. One mile (80 chains) is 1,609.344 m. When countries like Australia, Canada, and India transitioned to metric, millions of chain-based property descriptions had to be converted to meters. This conversion remains important for interpreting pre-metric land records.

## Good to Know

This is the one chain conversion that has real ongoing practical importance. Land registries in countries that metricated from the British system routinely convert chains to meters when processing old deeds. It is not just a mathematical curiosity but a legal necessity.

## FAQ

### How many meters is 1 chain?

One chain equals exactly 20.1168 meters. This derives from 1 chain = 66 feet, and 1 foot = 0.3048 m, so 66 x 0.3048 = 20.1168 m.

### How do I convert chains to meters?

Multiply the number of chains by 20.1168. For example, 15 chains = 15 x 20.1168 = 301.752 meters. For rough estimation, multiply chains by 20.

### When is this conversion needed?

When interpreting historical property surveys for modern land registries, GIS mapping, construction planning, or legal boundary disputes. Many English-speaking countries still have property records in chains that need metric conversion.

## Non-Frequently Asked Questions

### Is a chain about 20 meters or about 20 meters?

A chain is 20.1168 meters. So yes, about 20 meters. But that extra 0.1168 meters (11.7 cm) matters in land surveying. Over 80 chains (1 mile), the difference adds up to 9.3 meters. Close enough to lose a lawsuit over.

### Do Olympic athletes know how far a chain is?

A chain (20.12 m) is almost exactly the length of one 20-meter sprint mark. Usain Bolt covers a chain in about 1.9 seconds. The fastest surveyor in history probably needed about 15 seconds to measure one. Different types of athletes.

### If I laid a chain across a swimming pool, would it fit?

An Olympic pool is 50 meters. A chain is 20.12 meters. So 2.5 chains fit across a pool. Your chain would reach from one end to about the 20-meter mark. The lifeguard would probably ask you to stop.
