# What is the SI unit for speed?

The metric system of measurement in mathematics is the set of standard units defined to measure length, weight, and capacity.

## Answer: The SI unit for speed is meter per second (m/s).

Speed can be calculated by the formula: speed = distance/time.

**Explanation:**

To find the unit of speed we need to know the units for distance and time first.

The standard unit (SI) for measurement of distance is meter (m) and time is second (s), so the unit of speed will be in meters per second (m/s).
