## 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 90 centimeters into kilometers we have to multiply 90 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

90 cm → L_{(km)}

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

L_{(km)} = 90 cm × 1.0E-5 km

L_{(km)} = 0.0009 km

The final result is:

90 cm → 0.0009 km

We conclude that **90 centimeters is equivalent to 0.0009 kilometers**:

90 centimeters = 0.0009 kilometers

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 kilometer is equal to 1111.1111111111 × 90 centimeters**.

Another way is saying that *90 centimeters is equal to 1 ÷ 1111.1111111111 kilometers*.

## Approximate result

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

90 cm ≅ 0.001 km

An alternative is also that *one kilometer is approximately one thousand one hundred eleven point one one one times ninety centimeters*.
