and

1 m/s = 2.236936292054402 mph =3.3 kph =1.943844492440605 knots=3.280839895013123 ft/s =0.0029386414601757 mach ................................

id like to use sec/meters as the only option

as I said

or whatever then just convert it to the desired display format

to have any chance of doing this efficiently we need to know
min and maximum for each of these quantities
1 velocity
2 distance
3 time
otherwise its just pissing in the wind
