Knots to m/s (Knots to Meters per Second) Converter
1 knot equals 0.51444444 meters per second — multiply knots by 0.51444444 to convert. A knot is one nautical mile (1,852 meters) per hour, and dividing 1,852 by 3,600 seconds gives 0.51444444 m/s.
The formula
Multiply the knot value by 0.51444444 to get meters per second:
m/s = kn × 0.51444444
For example, 20 kn × 0.51444444 = 10.288889 m/s. To reverse, divide m/s by 0.51444444 (or multiply by 1.943844).

Where this conversion is used
Meteorologists and oceanographers frequently report wind and current speeds in knots but perform calculations in the SI unit of meters per second. Engineers modeling wind loads, sailors analyzing sensor data, and scientists processing marine measurements all rely on this conversion to move between the reporting convention and the computational standard.
FAQ
How many m/s are in a knot?
One knot equals 0.51444444 m/s. Multiply the knot figure by 0.51444444 — for example, 10 kn = 5.1444444 m/s.
What is the formula to convert knots to m/s?
Use m/s = kn × 0.51444444. The tool applies this exact factor automatically so you never round by hand.
How do I convert m/s back to knots?
Divide by 0.51444444, or multiply by 1.943844. For instance, 5.1444444 m/s = 10 kn.
Is the conversion exact?
It is exact to the nautical mile definition (1852 m); 0.51444444 is 1852 ÷ 3600 rounded to eight places.
