The Units of Capacity
• Capacity:
It is the amount a container can hold.

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

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
data.

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.
