## 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 12.1 centimeters into kilometers we have to multiply 12.1 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

12.1 cm → L(km)

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

L(km) = 12.1 cm × 1.0E-5 km

L(km) = 0.000121 km

The final result is:

12.1 cm → 0.000121 km

We conclude that 12.1 centimeters is equivalent to 0.000121 kilometers:

12.1 centimeters = 0.000121 kilometers

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 8264.4628099174 × 12.1 centimeters.
