FAQ
What is the conversion factor from kn to cm/s?
1 kn equals 51.44444 cm/s. To convert, multiply the value in knots by 51.44444.
How do I convert 1 kn to cm/s?
1 kn = 51.4444 cm/s. For any value, multiply by 51.44444.
How do I convert cm/s back to kn?
Divide by the same factor — or equivalently, multiply by 0.01943844. So 1 cm/s = 0.0194384 kn.
When would I need to convert knot to centimetre 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).
