The Cookio was built out of a frustration every home baker knows well — following a recipe carefully, measuring precisely, and still ending up with a dense loaf or a flat cake. Nine times out of ten, the culprit isn't technique. It's measurement. Most online unit converters treat every ingredient the same way: 1 cup = 240 grams, the weight of water. But 1 cup of all-purpose flour is actually 125 grams. Honey is 340 grams. Cocoa powder is 85 grams. These differences aren't small — they're the difference between a recipe working and failing. We built The Cookio to fix this — a free, open tool hub where every conversion is ingredient-specific, sourced from laboratory-tested data, and presented without ads cluttering the calculator or paywalls blocking the answer.
