Cooking measurements standardize recipe quantities for consistent results. US recipes use volume (cups, tablespoons); professional kitchens typically use weight (grams).
Volume Equivalents
- 3 teaspoons = 1 tablespoon
- 16 tablespoons = 1 cup
- 2 cups = 1 pint
- 4 cups = 1 quart
- 4 quarts = 1 gallon
Weight vs. Volume
1 cup of flour ≈ 120–130 g (varies by how you scoop). 1 cup of butter = 227 g. 1 cup of sugar = 200 g. Weight is more accurate and preferred for baking.
Why Professional Bakers Weigh Instead of Scoop
A cup of flour can weigh anywhere from 120 to 150 grams depending on how it's scooped (packed vs. spooned-and-leveled) — a 25% variance that can meaningfully change a baked good's texture. Weighing ingredients in grams eliminates this variability entirely, which is why professional and serious home bakers increasingly favor kitchen scales over cup measures for anything beyond casual cooking.
Liquid vs. Dry Measuring Cups
Liquid measuring cups (with a spout, filled to a line below the rim) and dry measuring cups (filled level with the top) are not interchangeable for precise recipes — the different shapes make it hard to accurately level a liquid cup or avoid spilling a dry cup filled to a marked line.
