Unit 11: Lesson 1 Target/Objective: I can convert between metric and customary units of mass and weight.

Math Message Table Leaders: Get SRBs for your table Let’s read pg. 140 together

Unit 11: Vocabulary & Notes The standard unit for weight in the metric system is the gram. – Example: a paper clip equals about 1 gram Heavier weights are measured in kilograms – Example: a dictionary equals 1 kilogram

Notes Cont’d The standard units for weight in the U.S. customary system are the ounce (oz) and the pound (lb). Heavier weights are measured in pounds. – Example: 1 oz equals a slice of bread – Example: 1 lb equals a can of soda

Metric Units 1 gram = 1,000 milligrams 1 kilogram = 1,000 grams 1 ton = 1,000 kilograms U.S. Customary Units 1 pound = 16 ounces 1 ton = 2,000 pounds Equivalencies between Metric & U.S. 1 ounce = 28 gram 1 kilogram = 2.2 pounds

Metric Questions What might be measured in… Milligrams? – Medicine Grams? – Food Kilograms? – Body weight Metric Ton? – A whale &/or a dump truck

Unit 11: Vocabulary & Notes Mass is a measure of how much matter something contains Weight is a measure of how strongly gravity pulls downwards. When scales show "kg" or "lb" it is just an estimate of the mass above them

Weight vs. Mass If you went to the moon and weighed yourself, would you weigh more or less than you do on Earth? Less Why? Gravity is weaker on the moon than it is on Earth. Weight is how hard gravity is pulling on it. Mass only changes if you remove something.
