Cooking Math Playbook: Measurements, Servings and Oven Temperatures

Cooking math is mostly ratio math. Convert the measurement, keep the proportions steady and know when an estimate is good enough.

Volume measurements

Teaspoons, tablespoons, cups and milliliters are volume units. The Cooking Conversion Calculator helps when a recipe uses a measurement you do not have nearby.

Scaling servings

If a recipe serves 4 and you want 6 servings, multiply each ingredient by 6 divided by 4. That ratio is the whole trick. The Recipe Scaler handles one ingredient at a time so you can move through a recipe line by line.

Where cooking estimates get messy

Flour, sugar, chopped vegetables and grated cheese can vary depending on packing and density. For casual cooking, volume conversion is usually fine. For baking, weight can be more consistent.

Temperature and timing

Oven temperatures often need Celsius to Fahrenheit conversion. Prep time, cook time and rest time are separate blocks, so add them like a schedule rather than assuming the recipe title tells the full story.

Play it: resize dinner without guessing

Open the Recipe Scaler. Enter ingredient amount 2, original servings 4 and new servings 7. That tells you what happens when dinner grows from four people to seven.

Then open Cooking Conversions and convert 1 cup to tablespoons. Use the two results together: one calculator changes the serving ratio, the other changes the measuring unit.
