Food Calculators

Food math is the kind of math you don't want to do in your head while the oven is preheating. The calculators in this category cover the practical questions that come up around recipes and entertaining — how much coffee per pot, how long an egg needs to boil, how many slices a loaf gives you, how much to buy when you're feeding a crowd. Every tool runs in your browser, uses concrete units (grams, millilitres, minutes), and shows enough of the math that you can sanity-check the answer. Pick the calculator that matches your question, enter the numbers, and get on with cooking.
