1. Lesson 3 Measuring with SI and Metric Units

2. Units of Measurement There are two types of units:
SI Units
There are two types of units:
fundamental (or base) units;
derived units.

3. There are 7 Fundamental (Base) SI Units
Powers of ten are used for convenience with smaller or larger units in the SI system.
