hey it's Kalei and in this lesson we're
going to talk about the different units
used in the United States for measuring
the volume of liquids when you hear the
word gallon you might think of a gallon
of milk those big plastic jugs of milk
at the grocery store and that is correct
those jugs each hold one gallon of milk
a gallon is the largest unit used to
measure the volume of liquids similarly
to a gallon of milk we also see quarts
of milk in the grocery store these are
the tall cardboard containers each
container holds exactly one quart of
milk a quart is the second largest unit
used for measuring volume of liquids a
pint might be harder to visualize
usually when you order a soda or a
lemonade at a restaurant it comes in a
pint sized glass you can also buy pints
of ice cream at the grocery store a pint
is the second smallest unit for
measuring the volume of liquids when
someone says they need a cup of coffee
they really mean it most mugs are
exactly one cup a cup is the smallest
unit of measurement for the volume of
liquids now how do these units all
compare to each other here we have them
ordered from largest volume to the
smallest volume now let's look at how
these units compare to each other
numerically or with values let's compare
cups and pints there are two cups in one
pint so we can say two cups is equal to
one pint now let's compare pints to
quarts there are two pints in one quart
so we can say two pints is equal to one
Court now let's compare quarts to
gallons there are four quarts in one
gallon so we can say four quarts is
equal to one gallon I use a little trick
to remember this one quart sounds like
corridor and a corridor is 1/4 so there
are 4 quarts in one gallon using the
chart how many pints fit in six cups
well if I know that 2 cups is equal to
one pint then for these 2 cups here this
will be equal to 1
tight and these two here is equal to
another 1 pint and these two here are
equal to another 1 pint excuse my bad
drawings of pints so if we add all of
these pints up here we have three so six
cups equals three pints how many gallons
are in 8 quarts so remember these are
courts down here and there's four is
equal to one gallon so over here if I
count 1 2 3 4 here's 4 quarts those are
equal to one big gallon of milk and then
I have another 4 down here so that is
equal to another gallon so if I have 8
quarts that is equal to 2 gallons now
this one says how many quarts are in 4
pints so this is the court here 1 is
equal to 2 pints so here I have these
two pints is going to be equal to one
quart and these two pints is going to be
equal to one quart so that would give me
a total of two quarts is equal to four
pints
so now this one says how many cups are
in six pipes so I need to find my
conversion factor with cups and pints
and it says there's two cups in every
one pint so that means this one pint
here is equal to two cups some means
each of these is equal to two cups two
cups two cups all the way down the line
and so I could count the cups or I can
do a quick multiplication problem I know
that there's two for each of these so
two cups times how many pints again that
was six so that would give me two times
six twelve cups so there are twelve cups
in six pints now you know the four units
for measuring volume of liquids practice
what you've learned by doing the online
games and quizzes have fun and remember
to always be clever
