Conversion formula

The conversion factor from meters to kilometers is 0.001, which means that 1 meter is equal to 0.001 kilometers:

1 m = 0.001 km

To convert 400 meters into kilometers we have to multiply 400 by the conversion factor in order to get the length amount from meters to kilometers. We can also form a simple proportion to calculate the result:

1 m → 0.001 km

400 m → L_(km)

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

L_(km) = 400 m × 0.001 km

L_(km) = 0.4 km

The final result is:

400 m → 0.4 km

We conclude that 400 meters is equivalent to 0.4 kilometers:

400 meters = 0.4 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.5 × 400 meters.

Another way is saying that 400 meters is equal to 1 ÷ 2.5 kilometers.

Approximate result

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

400 m ≅ 0.4 km

An alternative is also that one kilometer is approximately two point five times four hundred meters.
