SI

The video tutorial explains the standard units of measurement used for different properties. It introduces the 7 basic units: kilogram for mass, meter for length, second for time, ampere for electric current, Calvin for temperature, MOL for the volume of a substance, and Candela for light intensity.

What is the primary purpose of standard units of measurement?

• To reduce the number of measurements

• To confuse scientists
