1 Metric Units of Mass, and Capacity

2 The Metric System The metric system of measurement is a decimal system that uses prefixes to relate the sizes of units to standard units. The standard unit of mass is the gram. The standard unit of capacity is the liter.

3 Metric Prefixes kilo1,000 hecto100 deka10 deci0.1 centi0.01 milli0.001

4 Mass – the amount of matter that an object has. The standard unit is a gram. A gram is about the mass (or, basically, the weight) of a paper clip. 1,000 grams make a kilogram. You would use kilograms to measure heavier things, like desks and people. A kilogram is roughly equivalent to the weight of a one liter bottle of water. A newborn baby weighs about 3 kg. A milligram is very small. It takes 1,000 mg to make a gram. An eyelash weighs about 1 mg.

5 Mass - weight In the metric system, all units are defined in terms of a basic unit. The basic unit of mass in the metric system is the gram. 5

6 Everyday items you could use to associate with mass in the metric system. milligram - a grain of salt gram - large paper clip kilogram - math textbook 6

7 Mass - grams 1 gram = 1000 milligrams 1 kilogram = 1000 grams 7

8 Capacity – the amount of liquid an object holds. The standard unit is a liter. A bottle of juice holds about a liter of liquid. 1,000 liters make a kiloliter. If you filled 2-3 bathtubs with water, you would have about a kL of water. A milliliter is very small. It takes 1,000 mL to make a liter. A couple of drops of water would be equivalent to 1 mL. You would use milliliters to measure how much liquid was in a glass, or a juice box, or a can of soda.

9 Capacity - volume In the metric system, all units are defined in terms of a basic unit. The basic unit of capacity in the metric system is the liter. 9

10 Everyday items you could use to associate with capacity in the metric system. milliliter - 10 drops of food coloring liter - a small pitcher of water kiloliter – hot tub or spa 10

11 Capacity - liters 1 liter = 1000 milliliters 1 kiloliter = 1000 liters 11
