Scaling a recipe is just multiplying every ingredient by one scale factor — desired servings divided by the original. Run each ingredient through it and the proportions stay intact. Keep the standard volume conversions nearby for when a recipe mixes cups, tablespoons and teaspoons.
How it’s calculated & sources
Scale factor = desired servings ÷ original servings. Multiply each ingredient amount by the factor. Conversions: 1 cup = 16 tbsp = 48 tsp = 8 fluid ounces.
Benchmark: standard U.S. volume conversions — 1 cup = 16 tbsp = 48 tsp = 8 fl oz; 1 tbsp = 3 tsp.

Frequently asked questions
Does everything scale linearly?
Most ingredients do, but cooking times, pan sizes and leavening or seasoning may need judgment — taste and check doneness when scaling a lot.
How do I halve an egg?
Beat the egg and use half by volume (about 2 tablespoons), or scale the recipe to use whole eggs.
