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 4200 centimeters into kilometers we have to multiply 4200 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

4200 cm → L_(km)

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

L_(km) = 4200 cm × 1.0E-5 km

L_(km) = 0.042 km

The final result is:

4200 cm → 0.042 km

We conclude that 4200 centimeters is equivalent to 0.042 kilometers:

4200 centimeters = 0.042 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 23.809523809524 × 4200 centimeters.

Another way is saying that 4200 centimeters is equal to 1 ÷ 23.809523809524 kilometers.

Approximate result

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

4200 cm ≅ 0.042 km

An alternative is also that one kilometer is approximately twenty-three point eight one times four thousand two hundred centimeters.
