How the Conversion Works
This calculator uses a two-step conversion process through meters (m) as the base unit, which is the standard unit of length in the International System of Units (SI).
Conversion Formula:
Step 1: Convert from km to meters (m)
Value in m = Input value ÷ 0.001
Step 2: Convert from meters (m) to mi
Result = Value in m × 0.000621371
