## 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 4 centimeters into kilometers we have to multiply 4 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

4 cm → L(km)

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

L(km) = 4 cm × 1.0E-5 km

L(km) = 4.0E-5 km

The final result is:

4 cm → 4.0E-5 km

We conclude that 4 centimeters is equivalent to 4.0E-5 kilometers:

4 centimeters = 4.0E-5 kilometers

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 25000 × 4 centimeters.

Another way is saying that 4 centimeters is equal to 1 ÷ 25000 kilometers.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four centimeters is approximately zero kilometers:

4 cm ≅ 0 km

An alternative is also that one kilometer is approximately twenty-five thousand times four centimeters.
