1. Units of Measurement
Why do we measure our world?

2. Basic Quantities We Measure: Length: How long or tall something is
Volume: The amount of space that something occupies or the amount of space something contains
Mass: The amount of matter that something is made of.
Temperature: The measure of how hot or cold something is.

3. Derived Quantities:
A derived quantity is a combination of two or more measurements.
Area: A measure of how much surface and object has
Area = Length x Width
Density: The amount of mass per volume. The amount of matter in a given space. (How tightly packed together an object is).
D = mass/volume

4. But the rest of the world, uses a different system of units...
In America, what units do we use to measure...
...length?
...volume?
...mass?
...temperature?
But the rest of the world, uses a different system of units...
