What is the unit for speed?

The unit for speed is measured in "meters per second" (m/s) in the International System of Units (SI). This unit represents the distance (in meters) traveled in one second.

Speed is a scalar quantity, representing just the magnitude of motion without considering its direction. It is the rate at which an object changes its position with respect to time.

However, there are other commonly used units for speed. For example, the kilometer per hour (km/h) is commonly used to measure the speed of vehicles. The conversion between meters per second and kilometers per hour is 1 m/s = 3.6 km/h.

Another unit for speed is the mile per hour (mph), often used in the United States and a few other countries. The conversion between meters per second and miles per hour is 1 m/s = 2.23694 mph.

When it comes to scientific calculations and measurements, the SI unit of meters per second is generally preferred due to its simplicity and universal acceptance.
