Hello Wayne
Using Floating point maths you can do the following.
milesperhour = meterpersecond / 0.44704
I calculated this by working out the following.
1 mile = 1609.344 meters
miles per second = meterspersecond / 1609.344
miles per minute = meterspersecond / (1609.344 / 60)
miles per hour = meterspersecond / ((1609.344 / 60) / 60)

if you can accept 1600 as an approximation for metres/mile, the calculation simplifies to:
1600/3600 = 4/9.
