A standard US recipe cup of water is about 237 mL. Most US recipes call for cups; weighing in grams is more reliable. In US gallons, that gives you: 1 cup = 0.0625 gal, 10 cup = 0.625 gal, 100 cup = 6.25 gal.
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.
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.
