## 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 20.8 centimeters into kilometers we have to multiply 20.8 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

20.8 cm → L(km)

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

L(km) = 20.8 cm × 1.0E-5 km

L(km) = 0.000208 km

The final result is:

20.8 cm → 0.000208 km

We conclude that 20.8 centimeters is equivalent to 0.000208 kilometers:

20.8 centimeters = 0.000208 kilometers

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 4807.6923076923 × 20.8 centimeters.

Another way is saying that 20.8 centimeters is equal to 1 ÷ 4807.6923076923 kilometers.

## Approximate result

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

20.8 cm ≅ 0 km

An alternative is also that one kilometer is approximately four thousand eight hundred seven point six nine two times twenty point eight centimeters.
