Recipe Scaler turns an ingredient list into something people can use. Change the servings and every amount recalculates, in fractions a cook can actually measure: 1½ cups, not 1.4999. Grams and millilitres round to numbers you can weigh, eggs stay whole eggs, and cups can become millilitres or grams the moment a visitor asks for metric. Everything happens in the browser, so there is no API, no keys and no backend.
