US Volume Measurement Hierarchy
The US system follows a neat hierarchy: 3 teaspoons = 1 tablespoon, 16 tablespoons = 1 cup, 2 cups = 1 pint, 2 pints = 1 quart, 4 quarts = 1 gallon. Understanding this chain makes mental estimation easy.
Metric Volume
The metric system uses milliliters (mL) and liters (L): 1000 mL = 1 L. Simple powers of 10 make conversions straightforward. One US cup = 236.588 mL, one fluid ounce = 29.5735 mL.
