1. Measurement Notes

2. The Metric System
The metric system is the measurement system used by all scientists
Based on multiples of 10

3. Types of Measurement LENGTH AND WIDTH Unit: Meter (m) Tool: Ruler
Meters, centimeters (cm), millimeters (mm)
Tool: Ruler
Area = length x width (cm2)

4. Types of Measurement VOLUME Unit: Liter (L) Tool: Graduated Cylinder
Milliliters (mL)
Tool: Graduated Cylinder
Volume = length x width x height (cm3)
Meniscus 

5. Types of Measurement MASS Unit: Gram (g) Tool: balance
Kilogram (kg) or milligram (mg)
Tool: balance
Density = mass  volume

6. Types of Measurement TEMPERATURE Unit: Celsius (°C) Tool: Thermometer
0 °C = the freezing point of water
32 °F
100 °C = the boiling point of water
212 °F

7. Conversions (see pg. 943) K H D B D C M Length Mass Volume Temperature
1 centimeter (cm) = 10 millimeters (mm)
1 meter (m) = 100 centimeters (cm)
1 meter (m) = 1000 millimeters (mm)
1000 meters (m) = 1 kilometer
1 gram (g) = 1000 milligrams (mg)
1000 grams (g) = 1 kilogram (kg)
Volume
Temperature
1 liter (L) = 1000 milliliters (mL)
1 cm3 = 1 mL
0 °C = freezing
100 °C = boiling

8. Practice Problems #1 Convert 5 meters to centimeters
500 cm
Convert 5000 meters to km
5 km
Convert 1500 mL to L
1.5 L

9. Practice Problems #2
Find the area of a table that is 30 cm wide and 1.5 meters long
Area = length x width
Area = 30 cm x 150 cm = 4500 cm2 (OR .45 m2)
Find the density of an object with a mass of 2.8 kg and a volume of 3.5 L
Density = Mass  Volume
Denstiy = 2.8 kg/3.5 L = .8 kg/L
Convert 2 kg to grams
2000 g
