About

Kitchen Calculator is a small collection of free calculators for home cooks and bakers, built to answer common questions fast: scaling a recipe, converting cups to grams, finding substitutions, converting pan sizes, and converting oven temperatures.

How the numbers work

Cup-to-gram weights come from published ingredient density references (flour ~125 g per cup, granulated sugar 200 g, butter 227 g). Pan conversions use the ratio of pan areas. Bake-time guidance is a rule of thumb backed by common baking practice; every oven differs, so verify doneness with a toothpick or thermometer.

Results are estimates for education, not a substitute for a tested recipe. Food-safety guidance always applies when handling raw eggs, flour, dairy, or perishables.
