Plain-language method
Use metres as the common reference unit.
Every supported length is represented by its exact value in metres. The input is converted to metres and then divided by the target unit’s metre value.
Defined international relationships—such as exactly 2.54 centimetres per inch—keep conversions consistent in either direction.
Target value = input × source-unit factor ÷ target-unit factor
