About gallons
The gallon is a unit with a split personality. The US Gallon (approx. 3.785 L) is based on the pre-1824 English wine gallon. The Imperial Gallon (approx. 4.546 L) used in the UK is about 20% larger. This divergence happened when Britain updated its standards in 1824, but the newly independent US stuck with the old wine gallon. Today, the US gallon is the standard for fuel and milk in the United States. gallons are commonly used in Gasoline sales (US), Milk jugs (US), Paint buckets, and Water consumption tracking, Aquarium sizes.
A large milk jug in the US is 1 gallon.
About cups
The measuring cup is the backbone of US home cooking. Standardized by Fannie Farmer in the 1890s to replace vague instructions like 'a tea-cup full,' the US Customary Cup is exactly 8 US fluid ounces. Note that the 'Metric Cup' used in Australia, Canada, and New Zealand is 250 mL, slightly larger than the US cup (approx. 237 mL). Baking with the wrong cup type can lead to recipe failures! cups are commonly used in Baking recipes (flour, sugar), Rice cooker measures, Coffee maker water reservoirs, and Liquid measuring cups.
A standard coffee mug is roughly 1.5 cups.
