Convert Meters per Second to Knots (m/s to kn)
1 meter per second (m/s) = 1.943844492 knots (kn). 1 kn = 0.5144444444 m/s. Example: 15 m/s = 15 × 1.943844492 = 29.15766739 kn.

How to Convert Meter per Second (Speed) to Knot
- 1 m/s = 1.943844492 kn
- 1 kn = 0.5144444444 m/s
- Example: convert 15 m/s to kn: 15 m/s = 15 × 1.943844492 kn = 29.15766739 kn
Formula
kn = m/s × 1.943844492441
Derivation from SI units:
- The SI unit of speed: one metre travelled per second.
- 1 knot = 1 nautical mile (1852 m) per hour = 0.514444… m/s.
Both units are defined exactly, so the factor is exact. Meter per Second (Speed) definition: meter per second; Knot definition: knot.
Worked examples
- A reading of 10 m/s converts to 19.43844492 kn.
10 m/s × 1.943844492 = 19.43844492 kn - A value of 30 m/s is 58.31533477 kn.
30 m/s × 1.943844492 = 58.31533477 kn

Frequently asked questions
How many knots are in 1 meter per second?
1 m/s = 1.943844492 kn.
How do I convert meters per second to knots?
Multiply the value in m/s by 1.943844492. For example, 15 m/s × 1.943844492 = 29.15766739 kn.
Is the m/s to kn conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
