Why convert m/s to mph?
Road speeds are posted in km/h in most countries but in mph in the US and UK; shipping and aviation use knots, physics and wind data use metres per second. Converting between them is routine for travel, sailing and sport.
One knot is exactly 1.852 km/h — one international nautical mile (1,852 m, standardised in 1929) per hour. And 100 km/h equals 62.137 mph or 27.778 m/s.
