m/s to Knots formula and what each symbol means
kn = m/s × 1.943844
| Symbol | Meaning |
|---|---|
| m/s | Meter per second |
| kn | Knot |
m/s to Knots examples
1 m/s
1 m/s × 1.943844 = 1.943844 kn.
10 m/s
10 m/s × 1.943844 = 19.43844 kn.
100 m/s
100 m/s × 1.943844 = 194.3844 kn.
m/s compared with Knots
One m/s is 1.944 times as large as one kn, so your number gets bigger when you convert m/s to knots and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About m/s and knots
Meter per second (m/s): The SI unit of speed. Knot (kn): Nautical miles per hour, exactly 1852/3600 m/s.
Where m/s to knots conversions are used
Road signs use km/h or mph depending on the country, and aviation and shipping use knots. Sports results are quoted in m/s, km/h or mph.
How to calculate m/s to Knots step by step
- Enter the value in m/s (the starting unit).
- Multiply by 1.943844, because 1 m/s = 1.943844 kn.
- The product is the value in kn. To go back, divide by 1.943844 or multiply by 0.5144444.
