Cooking Measurement Conversions Every Home Cook Should Know
Three teaspoons in a tablespoon. Sixteen tablespoons in a cup. Knowing these by heart makes you faster and more confident in the kitchen.
The US measurement system for cooking is confusing because it mixes volume (cups, tablespoons) with weight (ounces, pounds) and uses the same word "ounce" for both. A fluid ounce is volume. A regular ounce is weight. They are not the same — 1 fluid ounce of honey weighs about 1.5 ounces because honey is denser than water.
The Essential Conversions
3 teaspoons = 1 tablespoon. 4 tablespoons = 1/4 cup. 16 tablespoons = 1 cup. 2 cups = 1 pint. 4 cups = 1 quart. 4 quarts = 1 gallon. 1 cup = 8 fluid ounces = 237 milliliters. 1 stick of butter = 1/2 cup = 8 tablespoons = 4 ounces = 113 grams. Memorize these and you will never need to look them up again.
Why Professional Bakers Use Weight
Volume measurements are inherently imprecise. One cup of flour can weigh anywhere from 120 to 155 grams depending on how you scoop it — a 30% variation that can mean the difference between a light, fluffy cake and a dense brick. A kitchen scale (about $15) and weight-based recipes eliminate this variable entirely. For cooking (soups, sauces, stir-fries), volume is fine. For baking, weight is strongly recommended.
