Conversion formula

The conversion factor from miles per hour to meters per second is 0.44704, which means that 1 mile per hour is equal to 0.44704 meters per second:

1 mph = 0.44704 m/s

To convert 278 miles per hour into meters per second we have to multiply 278 by the conversion factor in order to get the velocity amount from miles per hour to meters per second. We can also form a simple proportion to calculate the result:

1 mph → 0.44704 m/s

278 mph → V_(m/s)

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

V_(m/s) = 278 mph × 0.44704 m/s

V_(m/s) = 124.27712 m/s

The final result is:

278 mph → 124.27712 m/s

We conclude that 278 miles per hour is equivalent to 124.27712 meters per second:

278 miles per hour = 124.27712 meters per second

Alternative conversion
