How to Convert Knots to Meters per Second

To convert knots to meters per second, multiply the speed by the following conversion ratio: 0.5144444 meters per second/knot.

Since one knot is equal to 0.5144444 meters per second, you can use this simple formula to convert:

meters per second = knots × 0.5144444

The speed in meters per second is equal to the speed in knots multiplied by 0.5144444.

For example, here's how to convert 5 knots to meters per second using the formula above.

meters per second = (5 kn × 0.5144444) = 2.5722222 m/s

How Many Meters per Second Are in a Knot?

There are 0.5144444 meters per second in a knot, which is why we use this value in the formula above.

1 kn = 0.5144444 m/s|1 m/s = 1.9438445 kn

Our knot to meters per second calculator automatically converts your speed measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Knots and meters per second are both units used to measure speed. Keep reading to learn more about each unit.

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). [1]

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.

What Is a Meters per Second?

Coherent SI unit of velocity. It serves as a primary reference unit for measuring speed across scientific and practical applications. [2]

The meters per second is classified as an International System of Units (SI) unit of speed. Meters per Second can be abbreviated as m/s; for example, 1 meters per second can be written as 1 m/s.

As the primary coherent reference unit for speed in this category, all other speed units are mathematically anchored to the meters per second (m/s).

In practice, meters per second (m/s) are widely used across standard speed applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.

When converting speed between knots (kn) and meters per second (m/s), keep full floating-point precision (1 kn = 0.5144444 m/s; 1 m/s = 1.9438445 kn) during intermediate calculations and round only the final meters per second figure to match your instrument tolerance.
