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.
Kilometers/hour (km/h)
Definition: Kilometers per hour (symbol: km/h) is a unit of speed, expressing the number of kilometers traveled in one hour.
History/origin: Derived from the meter and the hour, it became the most popular unit for road traffic and everyday transport measurements as the world adopted the metric system.
Current use: It is the official unit for speed limits and vehicle speedometers in most countries, including all of Europe, Asia, and the Americas (except the USA).

How to Convert Meters/second (m/s) to Kilometers/hour (km/h)
1 mps = 3.6 kmh
1 kmh = 0.27777778 mps
Example: convert 15 mps to kmh:
15 mps = 15 × 3.6 kmh = 53.99999996 kmh
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 fastest land animal, the cheetah, can reach a top speed of about 110 km/h in short bursts. That is faster than most cars are allowed to drive on a highway!
