How to Remember Customary System Measurement Conversions: Cups, Pints, Quarts, Gallons
In the United States, we measure things using customary units. The volumetric measures are cups, pints, quarts, and gallons. Remembering these measurements and their conversions can be difficult. People of all ages struggle with knowing how many cups, pints, quarts, and gallons make up everyday things. Many school children have problems remembering the amounts and how to convert between measurements. Adults may struggle with these conversions while cooking. How many cups can your two-quart pot hold? How many pints of water do you need to drink each day?
There is an easy way to remember the measurements. This method can also be used to do the measurement conversions.
How to Remember Customary Unit Measurements
- Make conversions using the square method: To convert between cups and gallons you can draw a square and divide it in half multiple times. When you are done you will have a graphic representation of cups, pints, quarts, and gallons. If you need to convert measurements you can simply draw the squares and count the boxes.
To start off, get out a piece of paper. Draw one square on it. This square is one cup. A cup holds 8 ounces.
Take your square and draw a line from the top to the bottom, dividing it in half. Then draw a line from left to right. You will now have two rectangles. Each rectangle has two squares in it. The rectangles are pints. The squares are cups. Each pint has two cups.
The big box that now has four squares represents a quart.
Each quart has two pints or four cups.
We are going to take the big box with four squares and divide it in half a few more times. First, divide the left column in half by drawing a line up and down through it. Next, do the same thing to the right column. After that, draw a line dividing the top row in half left to right. Then, do the bottom row the same way. You should now have sixteen squares.
Each of the little squares is one cup. There are sixteen cups in a gallon.
Each of the big squares in one quart (notice how it sounds like quarter, or quarter gallon). There are four quarts in a gallon.
You can also see that 8 pints are in one gallon.
Notice how each big square has four little squares? There are four cups in a quart.
