What is the si unit for speed?

The SI unit for speed is meter per second (m/s). It is defined as the distance traveled by an object divided by the time taken to travel that distance. Other units commonly used to measure speed include kilometers per hour (km/h) and miles per hour (mph). In scientific contexts, it is important to use SI units because they are standardized and universally accepted, allowing for easy communication and comparison of data across countries and disciplines.
