Convert Meters to Chains - Length Converter

Definition used: 1 chain = 66 feet = 20.1168 metres. This follows the exact definition of the foot (0.3048 m) and the historical definition of the Gunter chain. The conversion is therefore an exact arithmetic mapping between units.

Calculation approach: convert metres to chains by dividing the metre value by 20.1168 (chains = metres / 20.1168). For presentation the tool supports configurable rounding; choose precision consistent with measurement uncertainty and application requirements.

Accuracy and reporting: arithmetic conversion is exact to the precision of the computer arithmetic, but measured lengths carry uncertainty. Follow NIST guidelines on unit use and uncertainty reporting and ISO guidance on quantities and units when documenting results.

Numerical issues: binary floating-point arithmetic follows common IEEE practices; for high-precision or bulk conversions use a numerical mode or library that conforms to IEEE 754 recommendations or a decimal arithmetic library if exact decimal rounding is required.

Use chains = metres ÷ 20.1168 for conversions between metres and Gunter's chains. The arithmetic mapping is exact given the unit definitions.

Always consider and report measurement uncertainty and choose display precision appropriate to your measurement's accuracy. Refer to the cited standards for guidance on units and uncertainty reporting.

Example 1: 1 metre → 1 ÷ 20.1168 = 0.049709695 chains (approx. 0.04971 chains when rounded to 5 significant digits).

Example 2: 20.1168 metres → 20.1168 ÷ 20.1168 = 1 chain.

Example 3: 100 metres → 100 ÷ 20.1168 = 4.9709695 chains (approx. 4.971 chains when rounded to 3 decimal places).
