Meters/second (m/s)
Definition: Meters per second (symbol: m/s) is the SI derived unit of both speed and velocity. It is defined as the distance in meters traveled divided by the time in seconds.
History/origin: As the metric system was formalized, the meter and the second became the core units for distance and time, making m/s the logical scientific standard for speed.
Current use: This is the primary unit for speed in physics, engineering, and almost all scientific research worldwide.
Knots (kn)
Definition: A knot (symbol: kn or kt) is a unit of speed equal to one nautical mile per hour, which is exactly 1.852 km/h.
History/origin: Historically, a "chip log" with knots tied in a line was used to measure speed. The number of knots that passed through a sailor's hands in a set time determined the ship's speed.
Current use: Knots are the universal standard for maritime and aerial navigation. Pilots and ship captains use knots to calculate travel time and distance over large bodies of water.

How to Convert Meters/second (m/s) to Knots (kn)
1 mps = 1.94384449 kn
1 kn = 0.51444444 mps
Example: convert 15 mps to kn:
15 mps = 15 × 1.94384449 kn = 29.15766741 kn
Did You Know?
- Did you know? The speed of light is exactly 299,792,458 meters per second! At this speed, you could circle the Earth 7.5 times in just one second.
- The term "Knot" comes from an old maritime tradition where sailors would throw a rope with knots tied at intervals into the water to measure how fast the ship was moving.
