For this course you need to know what properties are measured by the units meters, liters and grams. You should also become familiar with units having prefixes such as centimeters, milliliters and kilograms. These topics are presented in the pages of these sections as length, volume, mass, and metric system summary. Links to those pages are listed in the border on the left side of this page. If you are totally familiar with these units and prefixes, feel free to move on to the next topic "Unit Conversions". (Click on "Unit Conversions" above.)
