Power 1 hp = 745.7 W   1000 W = 1.341 hp
Force 1 lbf = 4.448 N   1 N = 0.2248 lbf
Mass 1 lbm = 0.4536 kg   1 kg = 2.205 lbm
Length 1 foot = 0.305 m   1 m = 3.281 feet
Length 1 inch = 0.0254 m   1 m = 39.37 inches
Speed 1 mph = 0.4469 m/s   1 m/s = 2.237 mph

I will leave the conversion factors for those, who are measuring the propeller diameter in townships or teaspoons, mass in scruples and force in kips as an example for the interested reader.
