The Metric System describes units of measurement including Celsius for temperature, grams for mass, and liters for volume. It also outlines metric prefixes like kilo for 1000 and milli for 0.001 that are used to modify metric units of distance, mass and volume. While weight depends on gravity, mass is a measure that does not change and is quantified using grams. A mnemonic is provided to help recall the metric prefixes used to convert between metric units of measurement.

2. 1. Metric Units: temperature ºC Celsius mass g gram volume L liter distance m meter Used to measure Symbol Unit

3. 2. Metric Prefixes: kilo - = 0.001 or 1/1000 deci- centi- milli- = 0.1 or 1/10 = 0.01 or 1/100 = 1000 hecto- = 100 deka- = 10

4. 3. Mass vs. Weight Weight depends on gravity while mass does not Mass is a measure of how much “stuff” is present Mass is measured in grams

5. 4. Converting Metric Units The following sentence can be used to help make a chart which will help in converting between metric units: K ing H enry da nced m errily d own c entral M ain m c d m da h k
