There are many different units of measurement that you’re probably familiar with. Now, let’s look at measuring tools and how to use them. Below you see the bubble figure for length, area, volume, mass and time.
The bubble figure is important to take note of because it tells you what to multiply or divide by to switch between the different units, whether you go from meters to centimeters or from square decimeter to square millimeter.
You may want to look at power of 10’s when working with units. Here is an overview:
Rule
Length: A one-dimensional unit, therefore you multiply or divide by
$$10.$$ |
Area: A two-dimensional unit, therefore you multiply or divide by
$$1{0}^{2}=100.$$ |
Volume: A three-dimensional device, therefore you multiply or divide by
$$1{0}^{3}=1000.$$ |
