Conversion formula

The conversion factor from kilometers to meters is 1000, which means that 1 kilometer is equal to 1000 meters:

1 km = 1000 m

To convert 31.5 kilometers into meters we have to multiply 31.5 by the conversion factor in order to get the length amount from kilometers to meters. We can also form a simple proportion to calculate the result:

1 km → 1000 m

31.5 km → L_(m)

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

L_(m) = 31.5 km × 1000 m

L_(m) = 31500 m

The final result is:

31.5 km → 31500 m

We conclude that 31.5 kilometers is equivalent to 31500 meters:

31.5 kilometers = 31500 meters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter is equal to 3.1746031746032E-5 × 31.5 kilometers.

Another way is saying that 31.5 kilometers is equal to 1 ÷ 3.1746031746032E-5 meters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that thirty-one point five kilometers is approximately thirty-one thousand five hundred meters:

31.5 km ≅ 31500 m

An alternative is also that one meter is approximately zero times thirty-one point five kilometers.
