Meter/Second to Knot (m/s to kn)
Result
1.943844492 Knot
Formula
kn = m/s × 1.943844492
1 m/s = 1.943844492 kn, and 1 kn = 0.5144444444 m/s.
Speed units are a length divided by a time: 1 km/h = 1/3.6 m/s, 1 mph = 0.44704 m/s exactly, and 1 knot = 1 nautical mile per hour = 1,852/3,600 m/s.
Worked examples
- 1 m/s × 1.943844492 = 1.9438445 kn
- 10 m/s × 1.943844492 = 19.438445 kn
- 100 m/s × 1.943844492 = 194.38445 kn
Common mistakes
- A knot is a nautical mile per hour, so 1 kn = 1.852 km/h and 1.15078 mph — not 1 mph.
- Weather services quote wind in km/h, m/s, mph or knots depending on country; check the unit before comparing forecasts.
