## 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 3 centimeters into kilometers we have to multiply 3 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

3 cm → L(km)

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

L(km) = 3 cm × 1.0E-5 km

L(km) = 3.0E-5 km

The final result is:

3 cm → 3.0E-5 km

We conclude that 3 centimeters is equivalent to 3.0E-5 kilometers:

3 centimeters = 3.0E-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 33333.333333333 × 3 centimeters.

Another way is saying that 3 centimeters is equal to 1 ÷ 33333.333333333 kilometers.

## Approximate result

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

3 cm ≅ 0 km

An alternative is also that one kilometer is approximately thirty-three thousand three hundred thirty-three point three three three times three centimeters.
