How it's calculated
Result = value × (m/s per from-unit) ÷ (m/s per to-unit) 1 km/h = 1/3.6 m/s · 1 mph = 0.44704 m/s · 1 kn = 1852 m/h
Every speed goes through metres per second. A mile per hour is exactly 0.44704 m/s and a knot is one nautical mile (1852 m) per hour, used at sea and in the air. 100 km/h is about 62 mph.
