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

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. 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 ...
