Convert Knots to Metres per second
1 knot is 0.514444 m/s. One knot is exactly 0.514444444444 metres per second.
One knot is 0.51444444 metres per second. To convert knots to metres per second, multiply by 0.51444444; to go the other way, divide by 0.51444444 or multiply by 1.9438445. The factor is exact rather than rounded: it follows from NIST Special Publication 811. One nautical mile per hour — exactly 1,852 metres per hour.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert knots to metres per second?
- 1.Take the measurement in knots.
- 2.Multiply by 0.51444444 — that is how many metres per second fit in one knot.
- 3.To go back the other way, divide by 0.51444444, or multiply by 1.9438445.

What are knots and metres per second?
- Knot (kn)
- One nautical mile per hour — exactly 1,852 metres per hour. Used at sea and in the air because a nautical mile is one minute of latitude, which makes navigation arithmetic simple.
- Metre per second (m/s)
- The SI unit of speed, and the one physics is done in. A brisk walk is about 1.4 m/s.
