How to Convert Millimeters per Second to Knots
To convert millimeters per second to knots, multiply the speed by the following conversion ratio: 0.0019438 knots/millimeters per second.
Since one millimeters per second is equal to 0.0019438 knots, you can use this simple formula to convert:
The speed in knots is equal to the speed in millimeters per second multiplied by 0.0019438.
For example, here's how to convert 5 millimeters per second to knots using the formula above.
How Many Knots Are in a Millimeters per Second?
There are 0.0019438 knots in a millimeters per second, which is why we use this value in the formula above.
Our millimeters per second to knot calculator automatically converts your speed measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Millimeters per Second and knots are both units used to measure speed. Keep reading to learn more about each unit.
What Is a Millimeters per Second?
A millimeters per second is a unit of speed equal to 1/1,000 of a meters per second (0.001 m/s). 3D printing and CNC speed unit equal to 0.001 m/s. [1]
The millimeters per second is classified as a metric and SI-compatible unit of speed. Millimeters per Second can be abbreviated as mm/s; for example, 1 millimeters per second can be written as 1 mm/s.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millimeters per second (mm/s) a convenient decimal multiple of the meters per second (m/s).
In practice, millimeters per second (mm/s) are widely used across fine-tolerance laboratory, analytical, and micro-scale speed measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Knot?
A knot is a unit of speed equal to 0.5144444 meters per second (m/s), the base unit for speed. One nautical mile per hour (1.852 km/h = 0.514444 m/s). [2]
The knot is classified as a standard unit of speed. Knots can be abbreviated as kn; for example, 1 knot can be written as 1 kn.
When working with knots (kn) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, knots (kn) are widely used across standard speed applications within international standard workflows, engineering documentation, and technical data sheets.
When converting speed between millimeters per second (mm/s) and knots (kn), keep full floating-point precision (1 mm/s = 0.0019438 kn; 1 kn = 514.4444444 mm/s) during intermediate calculations and round only the final knot figure to match your instrument tolerance.
