## Conversion formula

The conversion factor from kilometers per hour to meters per second is 0.277777777778, which means that 1 kilometer per hour is equal to 0.277777777778 meters per second:

1 km/h = 0.277777777778 m/s

To convert 503 kilometers per hour into meters per second we have to multiply 503 by the conversion factor in order to get the velocity amount from kilometers per hour to meters per second. We can also form a simple proportion to calculate the result:

1 km/h → 0.277777777778 m/s

503 km/h → V(m/s)

Solve the above proportion to obtain the velocity V in meters per second:

V(m/s) = 503 km/h × 0.277777777778 m/s

V(m/s) = 139.72222222233 m/s

The final result is:

503 km/h → 139.72222222233 m/s

We conclude that 503 kilometers per hour is equivalent to 139.72222222233 meters per second:

503 kilometers per hour = 139.72222222233 meters per second

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter per second is equal to 0.0071570576540698 × 503 kilometers per hour.

Another way is saying that 503 kilometers per hour is equal to 1 ÷ 0.0071570576540698 meters per second.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that five hundred three kilometers per hour is approximately one hundred thirty-nine point seven two two meters per second:

503 km/h ≅ 139.722 m/s

An alternative is also that one meter per second is approximately zero point zero zero seven times five hundred three kilometers per hour.
