Cooking unit converter: cups, grams, and oven temperatures
Convert cooking measurements, including cups to grams by ingredient, tablespoons to teaspoons, ounces to grams, and Fahrenheit to Celsius. Use decimals or recipe fractions.
Choose a measurement, enter the recipe’s amount, and convert it to the unit you want. For cups to grams, choose the ingredient too. Flour and sugar have different cup weights.
Use this tool without an account. It works with decimals and fractions, and the reference tables below explain the measurement conventions.
In this guide
Convert a cooking measurement
Use a decimal or fraction: 1.5, 1/2, 1 1/2, or 1½. US cups and metric cups have different volumes.
Converted amount
Rounded to at most three decimal places. Fluid ounces measure volume; ounces here measure weight.
Cups to grams needs an ingredient
Use the ingredient mode for a volume-to-weight conversion. These approximate weights follow King Arthur Baking’s ingredient chart. Packing, ingredient form, and your measuring technique can change the amount; use the recipe’s own gram weights when available.
| Ingredient | One US cup, approximately |
|---|---|
| All-purpose flour | 120 g |
| White granulated sugar | 198 g |
| Brown sugar, packed | 213 g |
| Almond flour | 96 g |
| Oats, old-fashioned or quick | 89 g |
For example, 1½ US cups of all-purpose flour becomes approximately 180 g using this reference. That estimate applies to the named ingredient. It should not be reused for almond flour, packed sugar, or a different preparation.
Check the cup and spoon convention
This tool labels US customary cups and spoons explicitly and offers a separate 250 mL metric cup. A recipe using a 240 mL cup or a different tablespoon convention needs that stated measure respected. You can enter its milliliters directly.
- 1 US tablespoon
- 3 US teaspoons
- 1 US cup
- 16 US tablespoons
- 1 metric cup
- 250 mL
A fluid ounce is a volume unit. An ounce by weight is a mass unit. The tool keeps those labels distinct so a recipe’s liquid measurement does not become a weight by accident.
Fahrenheit to Celsius changes the temperature number
To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9. To go the other way, multiply Celsius by 9/5 and add 32. For example, 350°F becomes approximately 176.667°C.
Keep the recipe’s conventional or fan-oven instructions in view. Converting a number does not tell you a new baking time, and changing the pan or recipe size needs its own review. Our recipe scaling guide covers those decisions.
Keep a conversion with the recipe you will cook
Preserve the source amount so you can check the change later. If you decide to use a different unit in your saved recipe, keep its ingredient line and any quantities in the directions consistent.
Changing units preserves the amount. Changing servings changes how much you make. Adapting a recipe toward a goal changes the dish itself. Use Brie’s recipe editing workflow to review a proposed adaptation, then plan with the version you chose.
Sources and measurement conventions
Reviewed October 5, 2026. Volume uses US customary ratios with a US cup of approximately 236.588 mL, plus an explicitly labeled 250 mL metric cup. Weight uses avoirdupois ounces and pounds. Ingredient estimates use the published cup weights for the named forms. Results display rounded values.
