How to convert knots to meters per second
Knots and Meters per Second both measure speed, so converting is a single multiplication. One kn equals 0.514444 m/s, so you multiply your knots value by 0.514444.
Formula: meters per second = knots × 0.514444. For example, 10 kn = 5.14444 m/s.

Knots and Meters per Second explained
Knots (kn): One nautical mile per hour, used in aviation and shipping.
Meters per Second (m/s): The SI unit of speed, the distance in metres covered each second.
When you'd convert knots to meters per second
You'll convert knots to meters per second whenever a measurement is given in one unit but you need it in the other — comparing knots and meters per second figures across regions, following a recipe or spec, or double-checking a number. Because 1 kn is exactly 0.514444 m/s, the result is precise every time.
