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 kilometers per hour into meters per second we have to multiply 438 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 km/h → V_(m/s)

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

V_(m/s) = 438 km/h × 0.277777777778 m/s

V_(m/s) = 121.66666666676 m/s

The final result is:

438 km/h → 121.66666666676 m/s

We conclude that 438 kilometers per hour is equivalent to 121.66666666676 meters per second:

438 kilometers per hour = 121.66666666676 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 0.0082191780821852 × 438 kilometers per hour.

Another way is saying that 438 kilometers per hour is equal to 1 ÷ 0.0082191780821852 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 kilometers per hour is approximately one hundred twenty-one point six six seven meters per second:

438 km/h ≅ 121.667 m/s

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