Accuracy and rounding
Use U.S. liquid measures for cups, teaspoons, tablespoons, pints, quarts, and gallons unless a recipe says metric or imperial.
Metric volume units are fixed, and cups, teaspoons, tablespoons, pints, quarts, and gallons use U.S. liquid measures unless imperial is named.
For recipes, round to the nearest useful spoon, cup, or milliliter. For containers and dosing, keep more precision in mL.
