All articlesComplete Guide to Cooking Unit Conversions
Kitchen measurement conversions are the most error-prone everyday conversions because cooking uses a mix of volume-based (cups, tablespoons), weight-based (grams, ounces), and even count-based ("1 stick of butter") measurements that vary between countries. US recipes use volume (cups, tablespoons), while European and professional recipes use weight (grams). Weight is inherently more accurate because 1 cup of flour can weigh between 120 g and 160 g depending on how it is scooped and packed. The Australian tablespoon (20 mL) differs from the US/UK tablespoon (15 mL), creating a 33% error if you follow an Australian recipe with US measuring spoons. Professional bakers strongly prefer weight measurements for consistency.
When to Use Cooking Conversions
- Adapting recipes between US volume measurements (cups, tablespoons) and European weight measurements (grams).
- Scaling recipes up or down — doubling a recipe is easier with grams than with "1 ¾ cups plus 2 tablespoons."
- Converting between US and Australian tablespoons (15 mL vs. 20 mL) when following recipes from different countries.
- Substituting ingredients where weight-to-volume ratios differ (e.g., 1 cup of sugar weighs 200 g, but 1 cup of flour weighs 125 g).
Common Cooking Conversion Mistakes
- 1Assuming all ingredients weigh the same per cup. 1 cup of water = 237 g, 1 cup of flour = 125 g, 1 cup of sugar = 200 g, 1 cup of honey = 340 g.
- 2Using liquid measuring cups for dry ingredients (or vice versa). The cup volume is the same, but measuring technique affects accuracy by up to 20%.
- 3Confusing fluid ounces (volume) with ounces (weight). 1 fl oz of water weighs about 1 oz, but 1 fl oz of honey weighs about 1.5 oz.
- 4Ignoring that a "dash" and a "pinch" are not standard measurements. A dash is roughly ⅛ teaspoon, and a pinch is about 1/16 teaspoon.
