CUSTOMARY AND METRIC UNITS

CUSTOMARY UNITS OF LENGTH
12 inches (in) = 1 foot (ft)
3 feet = 1 yard (yd)
5,280 feet = 1 mile (mi)
1,760 yards = 1 mile / METRIC UNITS OF LENGTH
10 millimeters (mm) = 1 centimeter (cm)
10 centimeters = 1 decimeter (dm)
10 decimeters = 1 meter (m)
1,000 meters = 1 kilometer (km)
CUSTOMARY UNITS OF CAPACITY
8 fluid ounces (fl oz) = 1 cup (c)
2 cups = 1 pint (pt)
2 pints = 1 quart (qt)
4 quarts = 1 gallon (gal) / METRIC UNITS OF CAPACITY
1,000 milliliters (mL) = 1 liter (L)
10 deciliters (dL) = 1 liter
CUSTOMARY UNITS OF WEIGHT
16 ounces (oz) = 1 pound (lb)
2,000 pounds = 1 ton (T) / METRIC UNITS OF MASS
1,000 milligrams (mg) = 1 gram (g)
1,000 grams = 1 kilogram (kg)

Customary Capacity

Once upon a time, in the kingdom of gallon, there lived four queens. Each queen had a prince and princess in her castles. Each prince and princess had 2 cats. Each cat has 8 fleas.

Example:

An African elephant can take 1 ½ gallons of water into its trunk for a drink. How many quarts are in 1 ½ gallons?

To solve:

Find the relationship between gallons and quarts.

Each gallon is ______quarts.

So ½ gallon is ______quarts.

1 ½ gal = ______qt + ______qt = 6 qt

Solution: ______

Examples:

8 qt = ______gal

What is the relationship between quarts and gallons? ______

Each gallon contains ______quarts. Therefore, 8 quarts is equal to ______gallons

______pt = 64 fl oz

What is the relationship between pints and fluid ounces? ______

(Hint: If you don’t know, figure out the relationship of fluid ounces and cups, and then cups to pints.)

Each pint contains ______fl oz. Therefore, 64 fluid ounces is equal to ______pints.
