## 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 499 kilometers per hour into meters per second we have to multiply 499 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

499 km/h → V(m/s)

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

V(m/s) = 499 km/h × 0.277777777778 m/s

V(m/s) = 138.61111111122 m/s

The final result is:

499 km/h → 138.61111111122 m/s

We conclude that 499 kilometers per hour is equivalent to 138.61111111122 meters per second:

499 kilometers per hour = 138.61111111122 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 0.0072144288577097 × 499 kilometers per hour.

Another way is saying that 499 kilometers per hour is equal to 1 ÷ 0.0072144288577097 meters per second.

## Approximate result

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

499 km/h ≅ 138.611 m/s

An alternative is also that one meter per second is approximately zero point zero zero seven times four hundred ninety-nine kilometers per hour.
