Knots to meters per second

1 knot in meters per second
1 kn = 0.51444 m/s
m/s = kn × 0.5144444444

To convert knots to meters per second, multiply by 0.5144444444. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works

The relationship is m/s = kn × 0.5144444444. Both units measure speed, so the conversion is a fixed factor that never changes.

Common questions

How many meters per second are in one knot?
One knot equals 0.51444 meters per second. m/s = kn × 0.5144444444.
How do you convert knots to meters per second?
Use m/s = kn × 0.5144444444. So 10 kn is 5.144444 m/s.
How many knots are in one meter per second?
One meter per second equals 1.943844 knots, which is the reverse of the conversion above.
