## 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 21.5 kilometers into meters we have to multiply 21.5 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

21.5 km → L(m)

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

L(m) = 21.5 km × 1000 m

L(m) = 21500 m

The final result is:

21.5 km → 21500 m

We conclude that 21.5 kilometers is equivalent to 21500 meters:

21.5 kilometers = 21500 meters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter is equal to 4.6511627906977E-5 × 21.5 kilometers.

Another way is saying that 21.5 kilometers is equal to 1 ÷ 4.6511627906977E-5 meters.

## Approximate result

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

21.5 km ≅ 21500 m

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