Cooking Calculators

Cups measure volume while grams measure weight, so the conversion depends on ingredient density. The Cups to Grams Converter on this page uses tested density values for flour, sugar, butter, rice, and other common ingredients, so 1 cup of all-purpose flour returns about 125 g while 1 cup of granulated sugar returns about 200 g. For best baking accuracy, use a kitchen scale and weigh the ingredient directly rather than converting.

Different ingredients have very different densities. One US cup is a fixed volume of 240 ml, but the weight inside that cup depends on the ingredient. Flour is light and fluffy, weighing around 125 g per cup, while granulated sugar is denser at about 200 g per cup, butter is roughly 227 g per cup, and water is exactly 240 g per cup. Our converters apply ingredient-specific densities so each conversion reflects real kitchen weights instead of using one generic factor.

Yes for everyday home baking. The converters use widely accepted reference densities that match the values used by King Arthur Baking, professional cookbook publishers, and major recipe sites. For competition pastry, sourdough hydration math, or commercial production, weigh ingredients directly on a digital scale rather than converting from volume, because how tightly flour is packed into a cup can vary by 10 to 15 percent.

Not always. The Recipe Scaler / Resizer multiplies every ingredient by the same factor, but salt, spice, leavening, and yeast do not always scale linearly. When you double a bread recipe, the dough rises in a single combined mass, so the same yeast percentage usually works, but doubling salt in a small soup or stew can taste over-seasoned. The tool flags these caveats so you can adjust seasoning to taste rather than blindly multiplying.

A US customary cup is 236.59 ml, a US legal cup used on nutrition labels is 240 ml, a metric cup is 250 ml, an Australian cup is also 250 ml, an Imperial UK cup is 284 ml, and a Japanese cup is 200 ml. The Ml to Cups Converter and Tablespoons to Cups Converter let you choose the cup standard so you can follow recipes from any country without guessing which volume the author meant.

Yes. Every cooking calculator here is mobile responsive and tested on phones, tablets, and desktop browsers. Inputs are large enough to tap with floury fingers, results update instantly, and the layout reflows for portrait screens so you can keep your phone propped on the counter while you bake or roast.

Yes. All conversions, scaling, dough math, and roast time calculations happen locally in your browser. Recipe ingredients you type, dough ball weights, caffeine entries, and serving counts never leave your device. Nothing is uploaded to a server, logged in a database, or shared with third parties, so you can use these tools to plan private menus or proprietary recipes without concern.

The Cooking Time / Roast Calculator and Air Fryer Conversion Calculator give research-backed starting estimates based on USDA internal temperature targets, weight per pound rules, and the standard minus 25°F and 20% less time air fryer rule. Always check meat doneness with an instant-read thermometer rather than trusting time alone, since oven calibration, meat thickness, and starting temperature all affect actual cook time.
