## Conversion formula

The conversion factor from centimeters to kilometers is 1.0E-5, which means that 1 centimeter is equal to 1.0E-5 kilometers:

1 cm = 1.0E-5 km

To convert 389 centimeters into kilometers we have to multiply 389 by the conversion factor in order to get the length amount from centimeters to kilometers. We can also form a simple proportion to calculate the result:

1 cm → 1.0E-5 km

389 cm → L(km)

Solve the above proportion to obtain the length L in kilometers:

L(km) = 389 cm × 1.0E-5 km

L(km) = 0.00389 km

The final result is:

389 cm → 0.00389 km

We conclude that 389 centimeters is equivalent to 0.00389 kilometers:

389 centimeters = 0.00389 kilometers
