How to Calculate Ingredient Ratios

Formula

Ratio = Amount A / Amount B

Scaled Amount = (Part / Total Parts) x Target Total

Ratios are the foundation of professional cooking. Knowing the ratio of flour to water in bread dough (about 5:3) means you can make any quantity.

Example Calculation

A vinaigrette uses 3 parts oil to 1 part vinegar. Scale to 500 mL total.

  1. 01Ratio: 3:1 (oil to vinegar).
  2. 02Total parts: 3 + 1 = 4.
  3. 03Oil: (3/4) x 500 = 375 mL.
  4. 04Vinegar: (1/4) x 500 = 125 mL.
