The Units of Capacity

• Capacity:

It is the amount a container can hold. Within the customary system, the common units for measuring capacity are fluid ounces, cups, pints, quarts, and gallons.

Examples: A standard cup of coffee. A can of coke is 12 fluid ounces. A gallon of milk.

Gallon

A customary unit of capacity. One gallon is equal to 4 quarts.

1 gal = 4 qt

Quart (qt.)

One quart is equal to 2 pints.1 qt = 2 pt

1tall glass of lemonade = 1 pint

Pint (pt.)

One pint ( approx. a tall glass of lemonade) is equal to 2 cups.

1 pt. = 2 cups

Fluid Ounce (fl.oz.)

8 fluid ounces is equal to 1 cup.8 fl oz = 1c.

What Equals What?1 liter = 1,000 milliliters

Litersarg

e We measure large things in liters.

A Milliliter is about a drop.

A drop of water.

An eyedropper of medicine.

Conversions in Metric!1,000 mL = 1 L

When converting L to mL, put 3 zeros in place of the L—since you’re multiplying by 1,000.

2 L = ___________ mL000

When converting mL to L, remove 3 zeros in place of the mL—since you’re dividing by 1,000.

7,000 mL = ___________ L

Ms. Itzhaki’s water cooler holds 5,000 mL of Kool-Aid. She has 2 bottles of Kool-Aid. Each bottle holds 2 L. Will the Kool-Aid fit in her water cooler?

Step One: Draw the picture to show what she has.

Customary Weight• 16 ounces (oz) = 1 pound (lb)• 2,000 pounds = 1 ton (T)

To change from a larger unit of measure to a

smaller unit, MULTIPLY.

To change from a smaller unit of measure to a larger unit, DIVIDE.

Units of Weight/Mass.Weight :

It is a measure of the heaviness of an object. (gravity)

Mass: The amount of matter in an object.

FYI…your mass is the same no matter where you are; however, your weight would change if you were on the moon.

The common units for measuring weight in the customary system are ounces, pounds, and tons.

Examples: A loaf of bread is a pound. A compact car weighs a ton.

Pound (lb.)

A pound is equal to 16 ounces.1 lb. = 16 ounces.

1 pound of bread = One 16 ounce Jelly jar.

Ounce (oz.):

16 ounce is one pound .16 (oz.) = 1 lb.

16 ounce jar = 1 pound cake

Ton (T) :

One ton is equal to 2000 pounds. 1 T = 2000 lbs.

A compact car weighs one ton or 2000 pounds.
