Kitchen calculators — recipes, dough & coffee
Scale an ingredient list, plan straight dough by baker’s percentages or work out coffee and brew-water amounts. Free to use, with no account needed.
Recipe scaler
Scale an ingredient list by servings, including fractions and mixed numbers. Keep original units, review unchanged lines and copy or download the scaled recipe.
Baker’s percentage calculator
Plan straight dough from flour weight or target dough weight. Calculate flour, water, salt, yeast and individual piece weights from baker’s percentages.
Coffee ratio calculator
Calculate coffee or brew-water mass at a custom ratio. Split a batch into servings and compare nearby ratios using the same water amount.
Use the right reference quantity
Recipe scaling multiplies ingredient quantities, baker’s percentages use flour mass as their reference, and coffee ratios compare dry coffee with input brew water. Each calculator names its reference so that servings, total dough and finished beverage quantities are not confused.
