Convert kn to m/s instantly, choose the displayed precision, and verify the result with the formula and reference table below.
Meter per second (m/s)
Rounded for display only; calculations retain full precision.
Rounding and precision rules
- Convr calculates first and rounds the displayed result only once, at the final step.
- The default is a maximum of 6 decimal places; trailing zeros are removed.
- Very small values that would appear as zero, and values of 10¹² or more, use scientific notation.
- Display precision is not measurement uncertainty. For scientific, engineering, or regulated work, retain only the digits justified by the source measurement.
Practical context
Understanding this conversion
Knots are standard for ships, aircraft, and related weather reports. Meters per second provide the coherent SI rate used in physics and engineering calculations.
The factor follows from the exact 1,852-meter nautical mile and 3,600 seconds per hour. Do not add “per hour” after knots when stating ordinary speed.

Calculation
Knot to Meter per second formula
m/s = kn × 0.514444
Calculations retain full precision and the result is rounded only for display.
Worked example
For 10 kn, the result is 5.144444 m/s. Substitute 10 kn into the formula to obtain 5.144444 m/s.
A numerical value expressed in meter per second is usually smaller than the same measurement expressed in knot, because 1 kn equals 0.514444 m/s.

Frequently asked questions
How many meters per second are in one knot?
One knot equals exactly 1852 divided by 3600 meters per second, or approximately 0.514444 m/s.
Is a knot a distance unit?
No. A knot is a speed equal to one nautical mile per hour.
How does Convr round Knot to Meter per second results?
Convr keeps full numeric precision during the calculation and rounds only the displayed result. The default is a maximum of 6 decimal places, with selectable precision on this page.
Can I convert negative or decimal knot values?
Yes. The converter accepts positive, negative, decimal, and scientific-notation values. Negative values are physically meaningful for some scales, such as temperature, but not for every measured quantity.
