## 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 4.9 centimeters into kilometers we have to multiply 4.9 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

4.9 cm → L_{(km)}

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

L_{(km)} = 4.9 cm × 1.0E-5 km

L_{(km)} = 4.9E-5 km

The final result is:

4.9 cm → 4.9E-5 km

We conclude that **4.9 centimeters is equivalent to 4.9E-5 kilometers**:

4.9 centimeters = 4.9E-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 20408.163265306 × 4.9 centimeters**.

Another way is saying that *4.9 centimeters is equal to 1 ÷ 20408.163265306 kilometers*.

## Approximate result

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

4.9 cm ≅ 0 km

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