Formula
knots = meters per second × 1.94384617e+0
Speed is distance per unit time. 1 m/s = 3.6 km/h. 1 mph = 1.609344 km/h. 1 knot = 1.852 km/h (one nautical mile per hour).
About Meters per second and Knots
Meters per second (m/s): The SI derived unit for speed (distance / time); 1 m/s = 3.6 km/h. Common uses: Physics and engineering calculations, wind speed in meteorology, sports analytics (sprint speeds), and any context where speed feeds into other equations.
Knots (kn): One nautical mile per hour; a nautical mile is 1,852 m, based on one minute of arc along a meridian (so the unit is tied to Earth's geometry). Common uses: Marine navigation (ship speeds), aviation (aircraft speeds), and meteorology (wind speeds in weather reports for sailing and flying).
How the conversion works
Speed is distance per unit time. 1 m/s = 3.6 km/h. 1 mph = 1.609344 km/h. 1 knot = 1.852 km/h (one nautical mile per hour).
The exact relationship is knots = meters per second × 1.94384617e+0, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between meters per second and knots comes up wherever speed measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
