2. Advantages of using the metric system include:
Based on the number ten
Used worldwide
Is a decimal system
Easy to convert
Has prefixes
Kilo, Hecto, Deka, Deci, Centi, Milli

3. Base Units 1. Meter —Measures Length a. Tool — ruler or meter stick
2. Liter — measures volume (the amount of space an object takes up)
a. Tool — graduated cylinder
b. An irregular shaped object uses the displacement method
c. A Ruler is also used to measure volume.
Volume = Length x Width x Height
**** 1 ml = 1 cm 3

4. The correct units for volume are:
For liquids: L (liter) or mL (milliliter)
For solids: cm3

5. Base Units Continued
3. Gram — measures mass (the amount of matter in an object)
a. Tool — triple beam balance

6. Other Metric Measurements
1. Newtons—measures weight (how much gravity is pulling on an object) Tool — spring scale

7. 2. Celsius - Measures temperature
Tool — thermometer
Boling point of water = 100°C
Freezing point of water = 0°C
Body temperature = 37°C
