Customary Capacity

• There are 4 main units of customary capacity!
• GallonsGal
• QuartsQt
• PintsPt
• Cups--C

Quarts
Here is a quart of milk.
5
Pints
Mason and Jelly Jars are about a pint.

Use the Big G!!
8
Draw the G for Gallon.
9
Add 4 Qs for Quarts.
10
Go P P at CCsPs for Pints, Cs for Cups
C
Then put 2 of these in each 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.
14
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.
15
Since 6 qt 12 pt, she needed to buy 12 pt!
16
Metric Capacity
There are 2 main units of metric capacity.
Liters--L
Milliliters--mL

g
We measure large things in liters.

18
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--thats multiplying by 1,000.
2 L ___________ mL
000
So, 2 L 2,000 mL
20
4 L _______________ mL
000
So, 4 L 4,000 mL
__________ mL 2 L
000
So, 2,000 mL 2 L
21
Ms. Itzhakis 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?
22
Step One Draw the picture to show what she has.

4L
2 L

2 L
Step Two Convert to the lower unit--mL.
4 L _______ mL
000
so 4 L 4,000 mL
23
Ms. Itzhakis 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!
