How it works
Every unit converts to meters per second first using exact definitions — 1 mph = 0.44704 m/s (the international mile, 1609.344 m, over 3600 seconds), 1 knot = 1852⁄3600 m/s (the international nautical mile is exactly 1852 m), and 1 ft/s = 0.3048 m/s (the international foot) — then from meters per second to the target unit.
Knots specifically measure nautical miles per hour, used in aviation and marine navigation rather than the statute mile mph uses on land — the two miles differ (1852 m vs. 1609.344 m), which is why 1 knot converts to about 1.15 mph rather than exactly 1.
