Convert Customary Units of Capacity | fl oz, c, pt, qt, and g

Welcome to Math with Mr. J. In this video, I'm going to cover how to convert customary units of capacity. So fluid ounces, cups, pints, quarts, and gallons. And along the left-hand side of your screen, we have seven practice conversions that we're going to go through together in order to get this down. Now, up top in blue, we have some notes that we're going to reference in order to do these conversions. Now, over in the blank area on the right side of your screen, I'm going to take those notes up top and create another way of putting the notes that I think is more helpful, but you can decide and use it if you'd like. So, again, these notes up top, or I'm going to draw something else that may be helpful to you. So we're going to start, and I would suggest you draw this out with me. If you find it helpful, then great. You can use it with your conversions. So we're going to draw a big G. And that G represents one gallon, so one gallon here. Next, we're going to draw four Qs. That represents four quarts equaling one gallon. So four Qs to fill that gallon. Yours is probably going to be neater than mine. So next, in each quart, we need two pints. So two pints equals one quart, and eight pints fills one gallon, or equals one gallon. Next, we need two cups in each pint. So we're going to put Cs in each pint. So a cup, if you can think back to your kitchen, and a measuring cup, one cup, and how many of those it would take to fill a gallon. So think of a gallon of milk. We would need 16 cups to fill a gallon. Now lastly, we have eight fluid ounces in one cup. Now that's just going to get too small to put eight fluid ounces in each of those Cs, so we are going to leave that one out of this here. So let's go into some conversions. And again, some people prefer to look at notes, like the notes up top, and some people prefer to look at the G, and then what fills that gallon. So as we go through, you can use both, or use whatever you prefer. So number one, two gallons equals how many pints. So the first thing we need to do, how many pints in one gallon? So if we take a look, we have eight pints in one gallon, so that means there's 16 pints in two gallons, so two times eight. Number two, six quarts equals how many pints? So in each Q, or each quart, there are two pints. So we want six of those. So six times two gives us 12 pints. Number three, three gallons equals how many quarts? There are four quarts in one gallon, so we need to do three gallons times four, which gives us 12 quarts. So three gallons equals 12 quarts. Again, four quarts in one, so there would be 12 in three, or three times four. Number four, 24 fluid ounces equals how many cups? So if we take a look up here, we know that eight fluid ounces creates one cup. So we need to split this 24 fluid ounces into groups of eight. Each one of those groups of eight is a cup, so we need to do 24 divided by eight, and that's going to give us three cups. Number five, five pints equals how many cups? So let's take a look. There are two cups in one pint, so we need to find out how many in five, so we can do five times two. That gives us ten cups. Number six, eight cups equals how many fluid ounces? All right, so there are eight fluid ounces in one cup, so we have eight groups of that eight fluid ounces, so eight times eight. That's going to give us 64 fluid ounces. Again, one cup has eight fluid ounces, so we have eight of them, so eight, eight, eight, eight times, so we would do eight times eight, and that equals 64. Number seven, 32 pints equals how many gallons? There are eight pints in one gallon, so we need to split this 32 pints into groups of eight. Each one of those groups of eight is one gallon, so we need to do 32 divided by eight, which gives us four gallons. So there you have it. There are some customary units of capacity conversions, along with some notes that I hope were helpful. Thanks so much for watching. Until next time, peace.
