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 ft to meters (m)

Value in m = Input value ÷ 3.28084

Step 2: Convert from meters (m) to km

Result = Value in m × 0.001

Simplified Formula:

Result = Input × 0.0003048
Where 0.0003048 is the conversion factor from ft to km

Example Calculation:

Let's convert 16 ft to km:

16 ft ÷ 3.28084 = 4.8768 m
4.8768 m × 0.001 = 0.004877 km

Result: 16 ft = 0.004877 km
