Formula

Formula
ch = m × 0.0497097

Multiply any value in metres by 0.0497097 to obtain the value in chains.

Worked example

Convert 100 m to ch.

  1. 01Start with 100 m.
  2. 02Multiply by the conversion factor: 100 × 0.0497097 = 4.97097 ch.
Result100 m = 4.97097 ch

FAQ

What is the conversion factor from m to ch?
1 m equals 0.0497097 ch. To convert, multiply the value in metres by 0.0497097.
How do I convert 1 m to ch?
1 m = 0.0497097 ch. For any value, multiply by 0.0497097.
How do I convert ch back to m?
Divide by the same factor — or equivalently, multiply by 20.1168. So 1 ch = 20.1168 m.
When would I need to convert metre to chain (Gunter's chain)?
Length conversions appear in piping, layout, and mechanical drawings — particularly when reconciling imperial fittings or instrument lengths with metric plant drawings.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
