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 milligrams1 kilogram = 1,000 grams1 ton = 1,000 kilograms

U.S. Customary Units

1 pound = 16 ounces1 ton = 2,000 pounds

Equivalencies between Metric & U.S.

1 ounce = 28 gram1 kilogram = 2.2 pounds

Metric QuestionsWhat 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.
