Speed Conversion: MPH to m/s - 15m/h-1

[JamesBX]

Ok for the life of me i can't remember how you get from say 15 miles per hour (15m/h) to 15mh-1?

Do you mean: 15 m/h to 15 m h^-1?

There is no conversion there, it's just a different way to write the same thing. Dividing by the power of a quantity is the same as multiplying by the negative power, so
mi / h = mi h^-1 (because you can read h as h¹) and for example ft / s² (as an acceleration) would be ft s^-2.

really no where to go.

$$\frac 1 x = x^{-1}$$
