How this baking calculator converts
Every cup-to-gram conversion relies on tested densities rather than uniform volume assumptions. Because bulk density varies dramatically between powdery flours, crystalline sugars, and liquid dairy, volume alone cannot guarantee precision. To convert any cup measurement to grams, this calculator applies the straightforward density formula:
Worked Example: If your recipe calls for 2.5 US cups of all-purpose flour, the calculator takes 2.5 and multiplies it by the King Arthur standard density of 120 grams per US cup:
When scaling batches for commercial production or large family gatherings, pairing volume conversions with our recipe scaling calculator prevents mathematical errors and keeps ingredient proportions perfectly balanced.
Free online kitchen converter: no download, no signup
Using this online kitchen converter requires no download or account registration. Rather than requiring users to install a heavy smartphone application from an app store, our lightweight web tool delivers instant kitchen calculations on Apple iOS, Android, Windows, and macOS devices without taking up device memory.
All mathematical operations execute locally via client-side JavaScript. No ingredient weights, recipe notes, or personal details are transmitted over the internet or saved to external databases. Whether you are standardizing sourdough formulas with our baker's percentage calculator or making quick substitutions on your kitchen counter, your baking data remains completely private.

Measuring tips
Baking is applied food science. Small variations in scooping technique or ingredient temperature create noticeable changes in dough elasticity, cake rise, and cookie spread. Follow these fundamental practices for consistent results:
Use a digital kitchen scale
A digital kitchen scale accurate to 1 gram eliminates volume measurement variability. Scooped cups measure volume, which fluctuates with settling, humidity, and sifting. Weighing ingredients directly in your mixing bowl ensures exact mass every time and reduces cleanup.
Spoon and level vs dip and sweep
Standard recipes assume flour is measured using the spoon and level method: fluff the flour with a fork or whisk, gently spoon it into the measuring cup without tapping, and sweep off excess with a straight edge. This yields exactly 120 grams per US cup.
In contrast, dipping the measuring cup directly into the flour bag (dip and sweep or scoop and sweep) compacts the powder, resulting in 130 to 140 grams per cup (and up to 170 grams if firmly packed). This unintended 10% to 40% excess flour dries out batters, creates tough doughs, and prevents proper cake rise.

Room-temperature ingredients
Unless a recipe specifically requires chilled butter for laminated pastry, bring butter, eggs, and milk to room temperature (65°F to 70°F / 18°C to 21°C). Softened butter creams smoothly with sugar, creating tiny air pockets that expand during baking for tender cakes. Cold milk or eggs curdle creamed butter and break emulsions.
If swapping liquid fats for solid dairy, consult our oil to butter converter to adjust for butter's 16% to 18% water content.
Oven temperature conversions
Oven temperatures can vary significantly between conventional and fan-assisted convection models. When baking in a convection oven, reduce the set temperature by 25°F (14°C to 15°C) to avoid over-browning crusts before the interior sets. Check doneness 5 to 10 minutes earlier than conventional bake times.
| Fahrenheit (°F) | Celsius (°C) | Convection Setting | Common Usage |
|---|---|---|---|
| 300°F | 149°C | 275°F (135°C) | Very Slow |
| 325°F | 163°C | 300°F (149°C) | Slow Oven |
| 350°F | 177°C | 325°F (163°C) | Moderate Oven (Standard Bake) |
| 375°F | 190°C | 350°F (177°C) | Moderate Hot |
| 400°F | 204°C | 375°F (190°C) | Hot Oven (Pastry / Cookies) |
| 425°F | 218°C | 400°F (204°C) | Hot Oven (Biscuits / Pizza) |
| 450°F | 232°C | 425°F (218°C) | Very Hot Oven (Bread Loaves) |
