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 438.2 kilometers per hour into meters per second we have to multiply 438.2 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

438.2 km/h → V_(m/s)

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

V_(m/s) = 438.2 km/h × 0.277777777778 m/s

V_(m/s) = 121.72222222232 m/s

The final result is:

438.2 km/h → 121.72222222232 m/s

We conclude that 438.2 kilometers per hour is equivalent to 121.72222222232 meters per second:

438.2 kilometers per hour = 121.72222222232 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 0.0082154267457716 × 438.2 kilometers per hour.

Another way is saying that 438.2 kilometers per hour is equal to 1 ÷ 0.0082154267457716 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 thirty-eight point two kilometers per hour is approximately one hundred twenty-one point seven two two meters per second:

438.2 km/h ≅ 121.722 m/s

An alternative is also that one meter per second is approximately zero point zero zero eight times four hundred thirty-eight point two kilometers per hour.
