```									Capacity—Measuring Liquid
A Third Grade Review!
Customary Capacity
• There are 4 main units of customary
capacity!

• Gallons—Gal
• Quarts—Qt
• Pints—Pt
• Cups--C
Gallons
Gallons   are used
i         to
a         measure
n
t         large
amounts.
Quarts

Here is a
quart of
milk.
Pints

Mason and Jelly
Jars are about a
pint.
Cups
Conversions

Use the Big G!!
Draw the G for Gallon.
Add 4 Q’s for Quarts.
Go P P at CCs…P’s for Pints,
C’s for Cups

C              …Then put 2 of
these in each
C             quart!

Which is more: 3 qt or 4 pt?
When I look at the Big G, I see that 4 pt is
the same as 2 qt.

That means that 3 qt is more than 4 pt.
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?

Click the button to
see the Big G.
Since 6 qt = 12 pt, she needed to
Metric Capacity
There are 2 main units of metric
capacity.

Liters--L         Milliliters--mL
Liters
a
r
g
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--that’s
multiplying by 1,000.
2 L = ___________ mL
000

So, 2 L = 2,000 mL
4 L = _______________ mL
000

So, 4 L = 4,000 mL

__________ mL = 2 L
000

So, 2,000 mL = 2 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.

2L      +     2L         =       4L

Step Two: Convert to the lower unit--mL.

4 L = _______ mL…
000

so 4 L = 4,000 mL
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 Three: Answer the Question.

YES, since she has 4,000 mL of water, it will fit
in her 5,000 mL container!
Congratulations!
You are now…
