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.
Miles/hour (mph)
Definition: Miles per hour (symbol: mph) is a British imperial and United States customary unit of speed, expressing the number of statute miles traveled in one hour.
History/origin: The mile per hour was established long before the metric system and was standardized during the British Empire. It remains a legacy in countries that haven't fully switched to metric road signs.
Current use: MPH is the primary unit for speed limits in the United States, the United Kingdom, and several offshore territories.

How to Convert Meters/second (m/s) to Miles/hour (mph)
1 mps = 2.23693629 mph
1 mph = 0.44704 mps
Example: convert 15 mps to mph:
15 mps = 15 × 2.23693629 mph = 33.55404438 mph
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 United States and the United Kingdom are among the few countries that still use Miles per Hour (mph) as the primary unit for road speed limits.
