what it does
One US gallon is 16 cups. Multiply gallons by 16 and the cups appear, which is how a bulk recipe becomes something a measuring cup can actually serve.
It shows up when a punch, brine or stock is planned by the gallon and portioned in cups, when a drink dispenser's capacity is quoted in gallons and the recipe is written in cups, when a garden spray is measured by the gallon but dosed in cups, and in any kitchen scaling from a family dinner to a school fête.
The shortcut is multiplication by 16: 1 gallon is 16 cups, 2 gallons is 32, half a gallon is 8, and a quart is 4. The whole US volume system is powers of two, so the ladder never surprises you.
