Factor1 mm/s = 0.001943844 kn
Converter
mm/s
Accepts numbers or expressions, e.g. 150 + 14.7
Result
kn
Rendered to 6 significant figures.
Formula
Formula
kn = mm/s × 0.001943844
Multiply any value in millimetres per second by 0.001943844 to obtain the value in knots.
Worked example
Convert 1000 mm/s to kn.
- 01Start with 1000 mm/s.
- 02Multiply by the conversion factor: 1000 × 0.001943844 = 1.94384 kn.
Result1000 mm/s = 1.94384 kn

FAQ
What is the conversion factor from mm/s to kn?
1 mm/s equals 0.001943844 kn. To convert, multiply the value in millimetres per second by 0.001943844.
How do I convert 1 mm/s to kn?
1 mm/s = 0.00194384 kn. For any value, multiply by 0.001943844.
How do I convert kn back to mm/s?
Divide by the same factor — or equivalently, multiply by 514.4444. So 1 kn = 514.444 mm/s.
When would I need to convert millimetre per second to knot?
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).
