An easy way to remember
Picture a big G for gallon. Inside it are four Qs (quarts). Inside each Q are two Ps (pints), and inside each P are two Cs (cups). So a gallon is 4 quarts, 8 pints or 16 cups.
Volume vs weight
Cups, pints and quarts measure volume. For water they line up neatly with weight (1 quart of water weighs about 946 g), but for other ingredients they don’t. To turn cups into grams for flour, sugar or butter, use the cups to grams converter.
