- The International System of Units (SI) is the modern form of the metric system and the world's most widely used system of measurement1. It is based on 7 base units:
- Meter (length)
- Kilogram (mass)
- Second (time)
- Ampere (electric current)
- Kelvin (temperature)
- Mole (quantity)
- Candela (brightness)2345.
