How to Convert Knots to Meters per Second

To convert a knot measurement to a meter per second measurement, multiply the speed by the conversion ratio.

Since one knot is equal to 0.514444 meters per second, you can use this simple formula to convert:

meters per second = knots × 0.514444

The speed in meters per second is equal to the knots multiplied by 0.514444.

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

5 kn = (5 × 0.514444) = 2.572222 m/s

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

What is a Knot?

One knot is equal to a speed of one nautical mile per hour,^[1] or one minute of latitude per hour.

Knots can be abbreviated as kn, and are also sometimes abbreviated as kt. For example, 1 knot can be written as 1 kn or 1 kt.

What Are Meters per Second?

Meters per second are a measurement of speed expressing the distance traveled in meters in one second.

The meter per second, or metre per second, is the SI derived unit for speed in the metric system. Meters per second can be abbreviated as m/s, and are also sometimes abbreviated as m/sec. For example, 1 meter per second can be written as 1 m/s or 1 m/sec.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.^[2]

Meters per second can be expressed using the formula:
v_m/s = d_m / t_sec

The velocity in meters per second is equal to the distance in meters divided by time in seconds.
