Speed Conversions

Here are a few of the most often needed conversion factors for speed. Speed, technically, is the scalar form of velocity, in that velocity (a vector) also provides direction of motion along with the value of speed.












Standard units = Meters per second (m/s)

foot per sec mile per hr cm per sec meter per sec km per hr knot
1 ft/s = 1 0.6818 30.48 0.3048 1.097 0.5925
1 mi/h = 1.467 1 44.70 0.4470 1.609 0.8689
1 cm/s = 3.281 * 10-2 2.237 * 10-2 1 0.01 3.600 * 10-2 1.944 * 10-2
1 m/s = 3.281 2.237 100 1 3.600 1.944
1 km/h = 0.9113 0.6214 27.78 0.2778 1 0.5400
1 knot = 1.688 1.151 51.44 0.5144 1.852 1

Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
