🍳Cooking Tools
Cooking tools for the math you actually run into in a kitchen: scaling a recipe up or down, swapping volume measurements for weight, adjusting for altitude, working out how many servings a cake yields, and substituting one ingredient for another in usable proportions. The arithmetic is rarely complicated. What makes it annoying is doing it in the middle of cooking, with a flour-covered phone and a recipe that lists tablespoons when your kitchen scale reads grams. The tools here are built to give the answer in one screen and remember your last inputs so the second halving of the recipe takes two seconds instead of a fresh hunt. The most common assumption that gets people in trouble is that one cup of any ingredient weighs the same; flour, sugar, oats, and shredded cheese are all different by a wide margin, which is why the cup-to-grams converters use per-ingredient densities rather than a single conversion factor. If you are new to the kitchen, start with the Cooking Conversion Calculator for unit work, the Cake Serving Calculator before any party where you have to feed a known number of guests, and the High-Altitude Kitchen Calculator if you live above about 3,000 feet and have been wondering why your cakes sink. Bakers should also look at Hydration Ratio and Baker's Percentage. The tools are usable from a phone in landscape with a wet finger.
