Getting Recipes and Measurements Right in the Kitchen

Cooking has more hidden math than it looks like — resizing a recipe, converting between volume and weight, and adjusting a time for a different appliance are all separate calculations that this category covers.

Scaling and converting

The Recipe Scaler resizes every ingredient in a recipe proportionally when you change the serving count — doubling a recipe, or shrinking one down for two people, without doing the multiplication ingredient by ingredient. The Cooking Measurement Converter handles the more common problem of converting between cups, tablespoons, and milliliters, or estimating the gram weight of a cup of a specific ingredient like flour or sugar.

Ovens and air fryers

The Cooking Time & Temperature Converter translates between Fahrenheit, Celsius, and UK gas marks, and offers a rule-of-thumb adjustment for cooking in a different pan size. The Air Fryer Converter applies the common conversion rule — a lower temperature and roughly 80% of the original time — to adapt a conventional oven recipe.

Planning ahead

The Weekly Meal Planner lays out breakfast, lunch, and dinner for every day in a simple, printable grid, and the Grocery Budget Calculator estimates a fair weekly food budget from your household size and how often you eat out.
