CUSTOMARY CAPACITY UNITS

GRADE 3


Hello, How are you doing?Today, we are going to start a new lesson on

customary capacity units.


Capacity Capacity is defined as a measure of dry or

liquid volume of a container.

Example – The capacity of the container is 1 gallon.


Customary Units of CapacityCustomary Units of capacity are – Cups (c) Pint (pt) Quart (qt) Gallon (gal)


Relation in Customary units

1 pint (pt) = 2 cups (c)

1 quart (qt) = 4 cups

1 quart (qt) = 2 pints (pt)

1 gallon = 4 quarts (qt)


Choose the better estimate.a) 10 cb) 10 qt


How many pints (pt) are there in a a) quart?b) a gallon

Answer- a) 2b) 8


How many quarts are there in 5 gallon?a) 10b) 20c) 30d) 40


Let us practice some problems now!


Write the objects in order from greatest to least capacity.Bathtub, glass of water, bucket


Convert 10 pt to cups


A big bottle of juice can be emptied in 8 cups. What is the capacity of the bottle of juice?


Compare using >, < or =a) 18 qt О 4.5 galb) 2 gal О 12 qt


Fill in the Blanks.a) --– qt = 4 ptb) --- c = 18 pt
