How the meters per second to knots converter works
Speeds convert through meters per second. 1 km/h is 1000/3600 m/s; 1 mph is 1609.344/3600 m/s; a knot is one nautical mile (1,852 m) per hour. Mach is shown against the standard sea-level speed of sound of 340.29 m/s and varies with altitude and temperature.
The US uses customary units (US gallon, short ton, °F) in daily life; NIST SP 811 gives the exact SI factors.

FAQFrequently asked questions about speed conversion
How many knots is 1 m/s?
1.9438 knots.
What is 10 m/s?
19.4 knots.
What is hurricane force?
33 m/s or more — 64 knots.
Why convert?
Because meteorological models output m/s while marine and aviation forecasts are issued in knots.
What is 1 knot in mph?
1.151 mph.
