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 400 centimeters into kilometers we have to multiply 400 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

400 cm → L_(km)

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

L_(km) = 400 cm × 1.0E-5 km

L_(km) = 0.004 km

The final result is:

400 cm → 0.004 km

We conclude that 400 centimeters is equivalent to 0.004 kilometers:

400 centimeters = 0.004 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 250 × 400 centimeters.

Another way is saying that 400 centimeters is equal to 1 ÷ 250 kilometers.

Approximate result

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

400 cm ≅ 0.004 km

An alternative is also that one kilometer is approximately two hundred fifty times four hundred centimeters.
