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.
A customary unit of capacity. One gallon is
equal to 4 quarts.
1 gal = 4 qt
Quart (qt.)
1tall glass of
lemonade = 1
One quart is equal to 2 pints.
1 qt = 2 pt
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.
The “Big G”
Try this one:
Ms. Itzhaki went to the store to buy 6 quarts of
milk. They were out of quarts! She had to get
pints instead. How many pints did she need to
bring home the same amount of milk?

Everything is related to the LITER:
What Equals What?
1 liter = 1,000 milliliters
We measure large things in liters.
A Milliliter is about a drop.
A drop of water.

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 = ___________ mL
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.
Step Two: Convert to the lower unit--mL.
4 L = _______ mL…
Step Three: Answer the Question.

We sampled sets of 8 m&m’s checking
for the number of red in each set. The
first sample we took had 7 reds out of 8
m&m’s or 7/8, the second sample had
only 3 out 8 m&m’s red or 3/8 .
Create a line plot using eighths, fourths,
halves, and wholes from the m&ms
• 1/8, 1/8, (2)
• 2/8, 2/8, (2)
• 3/8, 3/8, 3/8, 3/8, 3/8, (5)
• 4/8, 4/8, (2)
• 5/8, 5/8, 5/8, 5/8, (4)
• 6/8, 6/8, (2)
• 7/8, 7/8, 7/8, 7/8, (4)
• 8/8, 8/8, 8/8, 8/8. (4)
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)
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.

yesterday to answer the
following questions.

between the pack with most
amount of red m&m’s and
the pack with the least
amount of red m&m’s?
2. What is the amount that
most packs of m&m’s had?
Metric Units of Weight
Everything is related to the GRAM:
What Equals What?
1 kilogram (kg) = 1,000 grams (g)
1 gram = 1,000 milligrams (mg)
Metric Units of Weight/Mass
1 gram is about the
weight of a paperclip.
Gram (g): Measures weight
1000 grams is equal to 1 kilogram.
1000g = 1 kg.
Kilogram (kg.)
One Kilogram is equal to 1000 grams.
1 kg = 1000 g
1. If one paperclip has the mass of 1 gram and 1,000
paperclips have a mass of 1 kilogram, how many
kilograms are 8,000 paperclips?
2. Charlie's eraser has a mass of 20 grams. How many
milligrams are in 20 grams?
3. Steven goes to the grocery store and is looking at a
winter squash. It has a mass of 1.8 kilograms. How
many grams is the winter squash?
4. Using the information in question 3, determine the
number of milligrams in the winter squash.
5. A box contains 4 bags of sugar. The total mass of all
4 bags is 6 kg. What is the mass of each bag in
