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 mm to meters (m)
Value in m = Input value ÷ 1,000
Step 2: Convert from meters (m) to km
Result = Value in m × 0.001
Simplified Formula:
Result = Input × 0.000001
Where 0.000001 is the conversion factor from mm to km
Example Calculation:
Let's convert 16 mm to km:
16 mm ÷ 1,000 = 0.016 m 0.016 m × 0.001 = 1.600e-5 km Result: 16 mm = 1.600e-5 km
