About Converting Cubits to Chains
Cubit and Chain both measure length. Specifically: A common cubit is approximated as 18 inches, and a surveyor's chain is 66 feet.
Formula
chains = cubits × 0.0227272727273
This factor comes from each unit's defined relationship to the category's base unit: 1 cubit equals 0.4572 base units, and 1 chain equals 20.1168 base units, so dividing one by the other gives the direct cubit-to-chain factor of 0.0227272727273.
Simple example
1 cubit × 0.02272727273 = 0.0227272727 ch
1 cubit = 0.0227272727 chains.
Real-world example
10 cubit × 0.02272727273 = 0.2272727273 ch
10 cubits = 0.2272727273 chains.
