Cooking measurement conversions have a specific problem that general unit conversions do not: the same physical unit means different things depending on what you are measuring. A cup of flour weighs about 125 grams packed down or as little as 110 grams spooned loosely. A cup of honey weighs around 340 grams. Using volume to measure dry ingredients introduces a variability that can quietly ruin a recipe, even if the conversion factor itself is correct. This guide covers how to convert cooking measurements accurately, when to convert by volume versus weight, and the factors you need for the most common kitchen unit pairs. Step 1: Determine Whether You Are Converting Volume or Weight Cooking recipes use two distinct types of measurement that should not be mixed: volume (cups, tablespoons, teaspoons, milliliters, liters) and weight (grams, kilograms, ounces, pounds). For liquids, volume is generally reliable because liquids have consistent density. One cup of water and one cup of milk weigh nearly the same.…
