SI

The video tutorial explains the standard units of measurement used for various properties, focusing on the seven base units: kilogram for mass, meter for length, second for time, ampere for electric current, Kelvin for temperature, mole for the amount of substance, and candela for luminous intensity.

What is the primary purpose of defining standard units of measurement?

• To limit the use of technology in measurements

• To ensure consistency in measurements across different fields

• To make measurements more complex

• To create confusion in scientific studies
