Convert Knots to Meters per Second
kn to m/s · speed conversion
What are knots and meters per second?
A knot is one nautical mile per hour (1.852 km/h), used in aviation and shipping. Meters per second is the SI unit of speed, used in physics and science. For reference: a brisk walk is about 5 km/h (3 mph), and highway speed is around 100 km/h (62 mph).
How to convert knots to meters per second
1 kn = 0.514444 m/s. To convert, multiply the number of knots by 0.514444. For example, 5 kn = 2.57222 m/s, and 20 kn = 10.2889 m/s. To go the other way, multiply meters per second by 1.94385 (since 1 m/s = 1.94385 kn).

FAQ
What is 1 kn in m/s?
1 kn = 0.514444 m/s. To convert any amount, multiply the number of knots by 0.514444.
How do I convert meters per second back to knots?
Go the other way: 1 m/s = 1.94385 kn, so multiply meters per second by 1.94385 to get knots.
Is a knot bigger than a meters per second?
No — 1 kn is the smaller unit, equal to 0.514444 m/s (it takes 1.94385 kn to make one m/s).
Are these speed conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
