US gallons to cups multiplies by 16 — 1 US gallon = 4 quarts = 8 pints = 16 cups. A half gallon of milk is 8 cups; a gallon of stock is 16 cups. The doubling ladder (cup → pint → quart → gallon) makes US liquid scaling tidy once memorised. This is the customary cup (236.6 mL); the gallon itself is exactly 3.785411784 L, so a US gallon is 16 customary cups but about 15.77 metric cups.
Large-batch meal preppers and school cafeteria kitchens scaling a recipe written per gallon of soup or beverage base convert to cups for individual serving counts. 1 gal is 16 cups; 3 gal (a standard stockpot batch) is 48 cups; 0.5 gal is 8 cups. Because the US gallon-to-cup ratio is a clean whole number, catering software leans on it heavily for portion planning — a gallon of soup reliably serves 16 one-cup bowls before considering ladling loss.

A standard US milk jug holds 1 gal. An average car's fuel tank is 12–16 gal. In US cups, that gives you: 1 gal = 16 cup, 10 gal = 160 cup, 100 gal = 1600 cup.
The US liquid gallon equals exactly 3.785411784 liters, defined as 231 cubic inches. It is the standard fuel and milk unit in the United States. The US gallon is about 16.7% smaller than the UK (imperial) gallon (4.54609 L), so quoting fuel economy as 'mpg' without specifying the gallon can mislead by a wide margin.
The US legal cup, as used in nutrition labels, equals exactly 240 mL; the US customary cup, used in recipes, equals 236.5882365 mL (half a US liquid pint, or 8 US fluid ounces). Convertitive uses the customary value, which matches how most US cookbooks specify quantities. UK and Australian metric cups are 250 mL — yet another small but consequential difference.
