Convert nautical mile per second (nmi/s) to knot (kn). Use an editable speed converter, conversion formula, and reference table.

3,600

1 nmi/s = 3,600 kn

Calculated in your browser

Conversion formula

kn = nmi/s × 3,600

One nautical mile per second equals 3,600 knot. Multiply your value in nautical mile per second by this factor to get knot. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 nautical mile per second:
5 × 3,600 = 18,000 kn

About these measurements

Speed is distance traveled per unit of time.

The base reference used here is the meter per second. One nautical mile per second is 1,852 base units; one knot is 0.5144444444 base units.

Important distinctions

Mach is excluded because the speed of sound depends on medium and temperature.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions

Multiply the quantity in nmi/s by 3,600. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the knot to nautical mile per second converter.
