Top 10 Kitchen Math Tricks Every Home Cook Should Know

Kitchen math doesn’t need to be complicated. A few simple tricks can make cooking easier, faster, and more accurate.

1. Use ratios instead of exact measurements — for example, 1:2:3 for flour, fat, and sugar in basic doughs.
2. Convert cups to grams for accuracy, especially in baking.
3. Divide recipes by weight to scale them evenly.
4. Use the 80–90% rule for seasonings when doubling recipes.
5. Calculate cost per unit to compare grocery prices accurately.
6. Use per-100g values to compare nutrition labels quickly.
7. Batch-cook ingredients to reduce cost per serve.
8. Use a scale to portion meals for consistent serving sizes.
9. Convert oven temperatures between Celsius and Fahrenheit using simple formulas.
10. Use the tare button to measure multiple ingredients in one bowl.

These small techniques make cooking more predictable and help you get better results with less effort.
