Where you'll actually use this
Volume measures three-dimensional capacity — how much liquid a container holds or how much space an object occupies. Metric uses liters and milliliters; imperial uses gallons, quarts, pints, cups, and fluid ounces.
- Cooking
US recipes use cups and tablespoons; metric recipes use ml. A US cup is 236.6 ml — not 250 ml as in metric cups.
- Fuel
Pump prices show gallons in the US, liters almost everywhere else.
- Beverages
A US fluid ounce (29.57 ml) is slightly smaller than a UK fluid ounce (28.41 ml).
Common mistakes to avoid
- US gallon ≠ UK gallon
A US gallon is 3.785 L, a UK (imperial) gallon is 4.546 L — about 20% larger.
- Cups aren't universal
US cup = 236.6 ml. UK cup = 284 ml. Metric cup = 250 ml. Match the recipe origin.
