Free Online Food Calculators

Food is equal parts chemistry, math, and instinct — and our food calculators handle the numbers so you can focus on the cooking. Whether you're scaling a recipe for a crowd, converting cups to grams, calculating the nutritional breakdown of a homemade meal, or figuring out food cost for a restaurant menu, we've got tools for all of it. Need to know how many calories are in your recipe, or what the ideal butter-to-flour ratio is for that pastry? Trying to convert cooking temperatures, work out how long to cook a roast by weight, or calculate the right amount of yeast for your bread dough? Every question that trips you up mid-recipe has a calculator here. From everyday kitchen maths and nutrition tracking to food business costing and fermentation ratios, every tool is free, fast, and built for cooks of every level — whether you're meal prepping on a Monday or plating a five-course dinner.
