## 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 0.9 centimeters into kilometers we have to multiply 0.9 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

0.9 cm → L(km)

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

L(km) = 0.9 cm × 1.0E-5 km

L(km) = 9.0E-6 km

The final result is:

0.9 cm → 9.0E-6 km

We conclude that 0.9 centimeters is equivalent to 9.0E-6 kilometers:

0.9 centimeters = 9.0E-6 kilometers

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 111111.11111111 × 0.9 centimeters.

Another way is saying that 0.9 centimeters is equal to 1 ÷ 111111.11111111 kilometers.

## Approximate result

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

0.9 cm ≅ 0 km

An alternative is also that one kilometer is approximately one hundred eleven thousand one hundred eleven point one one one times zero point nine centimeters.
