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 30.8 centimeters into kilometers we have to multiply 30.8 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

30.8 cm → L_(km)

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

L_(km) = 30.8 cm × 1.0E-5 km

L_(km) = 0.000308 km

The final result is:

30.8 cm → 0.000308 km

We conclude that 30.8 centimeters is equivalent to 0.000308 kilometers:

30.8 centimeters = 0.000308 kilometers
