1. Chapter 3 Sections 3 and 5 Metric System -universal system of measurement used by scientists globally (SI) -based on scales/multiples of 10 -uses prefixes to convert numbers Length- size, distance -basic unit is the meter (m) 1 meter = 39.37 inches -Find your height in meters!!!

2. Mass- the amount of matter in an object -basic unit is the gram (g) 1 kg = 2.2 lbs -Find your weight in kilograms!! weight- measure of the pull of gravity on a given mass -mass is always the same, but weight can change -weight on the moon is 1/6 your weight on the Earth -Find your weight on the moon!!

3. Volume- the amount of space an object occupies -basic unit is the Liter (L) 1 L = 1.06 quarts **1 milliliter = 1 cm 3 HOW?? (length)(width)(height/thickness) = volume (cm)(cm)(cm) = cm 3 (cc) = mL

4. Temperature- how hot or cold something is -basic unit is Celsius (°C) Conversions: °F = 1.8(°C) + 32 °C = 5/9 (°F – 32) Kelvin = K = °C + 273 °C = K - 273 1) 15°C = ?°F 1.8(15) + 32 27 + 32 = 59°F

5. 2) 37°F = ?°C 5/9 (37-32) 5/9 (5) 2.78°C 3) above to Kelvin 2.78°C + 273 = 275.78K Try These! 37°C = ?°F72°F = ?°C and K
