FAQ
What is the conversion factor from ft/s to kn?
1 ft/s equals 0.5924838 kn. To convert, multiply the value in feet per second by 0.5924838.
How do I convert 1 ft/s to kn?
1 ft/s = 0.592484 kn. For any value, multiply by 0.5924838.
How do I convert kn back to ft/s?
Divide by the same factor — or equivalently, multiply by 1.68781. So 1 kn = 1.68781 ft/s.
When would I need to convert foot 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?
Yes. Both ft/s and kn are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
