Baking with Precision, Not Guesswork.
Cups To Grams was founded on a simple observation: more cakes, sourdough loaves, and pastries are ruined by volumetric measuring cups than by any other baking mistake.
The Problem with Measuring Cups
In home kitchens across North America, recipes are passed down in cups and tablespoons. Yet volume is inherently imprecise for dry ingredients. Depending on whether flour is sifted, gently spooned into a cup, or scooped directly from a deep bag, a single cup of flour can weigh anywhere from 115 grams to over 150 grams—a variation of more than 30%!
When a formula calls for 3 cups of flour, that small variability compounds into almost 100 extra grams of dry matter. The result? Dry, rubbery cakes, flat cookies, dense sandwich bread, and ruined weekend baking projects.
European, British, and Australian bakeries moved away from volumetric cups decades ago, relying on kitchen scales calibrated in grams. Cups To Grams was created to eliminate this barrier for home bakers everywhere, allowing anyone to convert heirloom or modern cup-based recipes into exact, reproducible metric weights.
How We Calibrate Ingredient Densities
Unlike generic conversion tools that multiply volume by a flat density number, our database is verified against authoritative culinary science benchmarks:
We align our all-purpose and specialty flour weights with King Arthur Baking Company's official standard of 120 grams per cup (spooned and leveled).
Sugars, dairy products, grains, and fats are cross-checked with empirical density data published by the United States Department of Agriculture.
We provide granular switches for US Customary (236.6ml), US Legal (240ml), Metric / Australian (250ml), and UK Imperial (284.1ml) cups.
Our tools are 100% free, responsive across all devices, contain no paywalls, and run instantly right in your browser with live calculations.
