1. The Metric System

2. System International (SI) A system of measurement that is used throughout the world, except in the United States and Myanmar. A system of measurement that is used throughout the world, except in the United States and Myanmar. All units related by factors of 10. All units related by factors of 10.

3. Basic Units of Measurement To measure:Basic Unit: To measure:Basic Unit: Length meter (m) Length meter (m) Volume (liquid) liter (l) Volume (liquid) liter (l) Mass (weight) gram (g) Mass (weight) gram (g) Temperature Celcius (C) Temperature Celcius (C)

5. Volume (liters) Two ways to calculate volume: Two ways to calculate volume: 1. length x width x height 2. Use a graduated cylinder, this is called displacement this is called displacement

6. Mass (grams) Amount of matter an object has. Amount of matter an object has. Mass does not equal weight! Mass does not equal weight! Mass is constant where weight is determined by the force of gravity pulling down an object Mass is constant where weight is determined by the force of gravity pulling down an object

7. Density Measurement of how much matter is inside an object. Measurement of how much matter is inside an object. Density can be calculated using this equation: Density can be calculated using this equation: Density= __Mass__ Density= __Mass__ Volume Volume

8. Celcius Water freezes at 0 degrees C. Water freezes at 0 degrees C. Water boils at 100 degrees C. Water boils at 100 degrees C.Conversion [°F]=[°C] * 9/5 + 32 [°F]=[°C] * 9/5 + 32 [°C]=[(°F-32) * 5/9)] [°C]=[(°F-32) * 5/9)]
