About Cooking Calc

What this site does

Cooking Calc converts ingredient measurements between volume (cups, tablespoons, teaspoons) and weight (grams, ounces) for accurate home cooking and baking. Every conversion is backed by an authoritative density table with sources cited.

Why density matters

Volume measurements (cups, tablespoons) are popular in US recipes but inherently variable: how you scoop, pack, or sift an ingredient changes how much actually fits in a measuring cup. Weight measurements (grams, ounces) are consistent — 100 grams of flour is always 100 grams of flour, regardless of how you measure.

Most US recipes use volume, but the recipes work because cooks know roughly how their measuring cup fills. When you’re following a recipe from another country, scaling a recipe up or down, or trying to be precise (especially in baking), converting to weight removes the guesswork.

Our methodology

For each ingredient in our table, we sourced gram-per-cup values from at least one of:

• King Arthur Ingredient Weight Chart
• USDA FoodData Central
• BBC Good Food Conversion Guide

When sources disagreed, we cross-referenced and chose the value most commonly cited across home-baking references. Each ingredient page lists its specific sources at the bottom.

For ingredients where packing matters (like brown sugar) or sifting matters (like flour), we list both packed/unpacked or sifted/unsifted values explicitly.
