Rendered to 6 significant figures.
Formula
Formula
m/s = kn × 0.5144444
Multiply any value in knots by 0.5144444 to obtain the value in metres per second.
Worked example
Convert 20 kn to m/s.
- 01Start with 20 kn.
- 02Multiply by the conversion factor: 20 × 0.5144444 = 10.2889 m/s.
Result20 kn = 10.2889 m/s

FAQ
What is the conversion factor from kn to m/s?
1 kn equals 0.5144444 m/s. To convert, multiply the value in knots by 0.5144444.
How do I convert 1 kn to m/s?
1 kn = 0.514444 m/s. For any value, multiply by 0.5144444.
How do I convert m/s back to kn?
Divide by the same factor — or equivalently, multiply by 1.943844. So 1 m/s = 1.94384 kn.
When would I need to convert knot to metre per second?
Velocity conversions are needed for fluid flow analysis (line velocity targets, erosional limits), gas-stream calculations, and equipment specs that mix m/s, ft/s and engineering speed units.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
