Cooking Calculator and Recipe Scaler
Halve, double or resize any recipe and convert between cups, grams, ounces, millilitres, tablespoons and teaspoons — with ingredient-aware weights so a cup of flour is not treated like a cup of water.

Weigh ingredients where you can — cup measures vary by up to 20% depending on how you scoop. Scale bake times more gently than quantities.
