Convert recipe measurements without opening five browser tabs. This free kitchen tool handles volume, weight, oven temperature, and ingredient-specific cups-to-grams estimates.
Cooking Measurement Converter
Uses a U.S. legal cup: 1 cup = 240 mL.
Why cups do not always convert to the same number of grams
A cup measures volume; a gram measures mass. One cup of honey weighs far more than one cup of flour, and even flour changes with scooping and packing. Use the ingredient mode for a practical estimate, but follow a recipe author’s stated weight whenever available. For baking, a kitchen scale is usually more repeatable than cups.
U.S. cup, metric cup, and fluid ounce
This tool uses the U.S. legal cup of 240 milliliters, commonly used on nutrition labels and convenient recipe conversions. Traditional U.S. customary calculations may use about 236.6 mL, while a metric cup is 250 mL. A U.S. fluid ounce is a volume unit and is not the same thing as an ounce of weight. Check the recipe’s country when precision matters.
Oven-temperature tip
The Fahrenheit/Celsius conversion is mathematical, but real ovens cycle above and below the set temperature. Convection settings may also require a lower temperature or shorter time than a conventional oven. Follow the appliance and recipe instructions, and use an oven thermometer when baking results are inconsistent.
Frequently asked questions
How accurate are the ingredient estimates?
They are rounded kitchen averages. Brand, moisture, grind, settling, and measuring technique can change the actual weight. The displayed grams-per-cup value makes the assumption visible.
Can I convert negative temperatures?
Yes. Temperature mode accepts negative values. Ingredient quantities should remain zero or greater.
Does this tool save my entries?
No. Calculations run only in your browser and are not uploaded.
