FEATURES • Scale recipes instantly using fractions • Convert ingredients between weight and volume measurements, including cups, grams, ounces, tablespoons, teaspoons, and more • Convert cups to grams and grams to cups using ingredient-specific conversion data • Save custom ingredients for even more accurate conversions • Convert volume, weight, temperature, and distance measurements • Enter amounts and view results using standard cooking fractions (1/2, 1/3, 3/4, etc.) RECIPE SCALING MADE EASY Quickly scale recipes up or down without reaching for a calculator. Whether you’re cooking for one person or feeding a crowd, Kitchen Calculator PRO makes doubling, halving, multiplying, and dividing recipe quantities fast and simple.
