To convert knots to meters per second, multiply the value by the conversion factor:

1 kn = 0.514444 m/s

For example: 10 kn = 5.1444 m/s

The Conversion Formula

To convert knots to meters per second, multiply the value by the conversion factor: 1 kn = 0.514444 m/s. For a worked example, suppose you need to convert 25 kn to meters per second: 25 × 0.514444 = 12.8611 m/s. To convert in the opposite direction, divide by 0.514444, or equivalently multiply by 1.9438.

About knots

The knot is a unit with a literal history: sailors used to measure speed by throwing a log overboard attached to a rope with knots tied at specific intervals. They counted the knots that slipped through their hands in a set time. One knot equals one nautical mile per hour. It remains the global standard for maritime and aviation operations. knots are commonly used in Ship speed, Aircraft airspeed, Cruise missile velocity, and Wind speed (Marine), Naval operations.

A large cruise ship travels at about 20-25 knots.

About meters per second

Meters per second (m/s) is the scientific standard for velocity. It is an SI derived unit. It is the language of physics, from ballistics to aerodynamics. The speed of light itself is defined exactly in these units (299,792,458 m/s). It is rarely used for road speeds but is standard for wind speed in meteorology outside the US. meters per second are commonly used in Physics calculations, Wind speed (Scientific), Projectile motion, and Sprinter speeds, Industrial machinery.

A typical human walking speed is about 1.4 m/s.

When Would You Convert knots to meters per second?

Converting between knots and meters per second is one of the most common speed conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 kn = 0.514444 m/s) memorized or bookmarked can save time in professional and everyday contexts alike.
