Knots to Meters per Second Conversion

Converting Knots (kn) to Meters per Second (m/s) is a common speed conversion. 1 kn equals 0.514444 m/s. For example, 100 kn is equal to 51.4444 m/s.

Quick Mental Math: Knots to Meters per Second

Multiply knots by 0.514 to estimate m/s.

Why is converting Knots to Meters per Second tricky?

Nautical knots are only used in maritime and aviation; unfamiliar to land-based users.

Quick Reference Values

1 kn = 0.514444 m/s. 5 kn = 2.57222 m/s. 10 kn = 5.14444 m/s. 25 kn = 12.8611 m/s. 50 kn = 25.7222 m/s. 100 kn = 51.4444 m/s.

What is Knots?

Knots (kn) is a unit of speed. A knot is a unit of speed equal to one nautical mile per hour. It precisely corresponds to 1.852 kilometers per hour or 0.51444 meters per second. The knot is internationally recognized for maritime and aviation speed measurements and is defined using the international nautical mile of exactly 1852 meters [nist-si-guide]. The knot originated from the practice of measuring speed at sea using a 'log line' with knots tied at regular intervals. The term and unit were standardized with the adoption of the international nautical mile in 1929 by the International Hydrographic Organization [nist-si-guide]. Knots are the standard speed unit in global maritime navigation and aviation. Countries and organizations like the International Maritime Organization (IMO) and International Civil Aviation Organization (ICAO) mandate its use for vessel and aircraft speed reporting [nist-si-guide].

What is Meters per Second?

Meters per Second (m/s) is a unit of speed. Meters per second (m/s) is the SI unit of speed, defined as the number of meters traveled in one second. It is the standard measure for velocity in physics and engineering, forming the base unit for speed in the International System of Units [bipm-si-brochure]. Adopted by the CGPM in 1960, meters per second was introduced to unify measurements of speed under the SI system. The meter was originally defined in 1793, but the m/s unit formalized with advancing scientific precision [cgpm-resolutions]. Meters per second is globally used in scientific research, engineering, and transportation industries. It is the primary speed unit in meteorology, fluid dynamics, and automotive testing, standardized by ISO and NIST [nist-si-guide].

Common Misspellings

People often search for this conversion using these alternate spellings: knotz, knotses, knotss, knotts, meter per second, meters per sec, metres per second, meter/sec. All of these refer to the Knots to Meters per Second conversion.
