### Units and Measurements Snapshot

In the Units and Measurements section of Physics we explore Physics tutorials which have been designed to teach you to identify the correct value in a list of possible answers for the exercises given at the end of each units and measurements tutorial. In this section, we cover tutorials which will allow you to answer the following questions competantly.

1. Why do we use units?
2. How are units classified?
3. What are the main systems of units used in science and daily life?
4. How do units help us find the missing formulae?
5. What are significant figures?
6. How do I interpret a result obtained during a measurement using significant figures?

### Units and Measurements Calculators

In addition to the Units and Measurements tutorials, we also provide online Units and Measurements Calculators which allow you to calculate specific Units and Measurements formula in support of the tutorials or to check and verify your own calculations in support of your homework, coursework or thesis.

The following Physics Calculators are provided in support of the Units and Measurements tutorials.
