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 6421 miles per hour into meters per second we have to multiply 6421 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

6421 mph → V_(m/s)

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

V_(m/s) = 6421 mph × 0.44704 m/s

V_(m/s) = 2870.44384 m/s

The final result is:

6421 mph → 2870.44384 m/s

We conclude that 6421 miles per hour is equivalent to 2870.44384 meters per second:
