Mixing Ratio Calculator

01 Set up your calculation

1. Enter 2–15 amounts separated by commas, all in the same mass or volume unit.
2. Enter a positive scale factor; for example, 2 doubles the mixture.
3. Use the component percentages to check the proportions and the scaled amounts to plan the new batch.

02 The relationship

For the assumptions behind these results, read the explanation below. You can also explore Alligation and Mass Percent.

03 A ratio preserves proportions

A mixing ratio describes relative amounts without fixing the batch size. Multiplying every amount by the same factor changes the total while leaving each percentage unchanged. This is useful for comparing formulations or scaling a nonreactive blend.

Use one consistent basis. Grams and milliliters cannot be combined in the same list without density information. If the list represents mass, the resulting percentages are mass percentages; if it represents volume, they are percentages of the entered component volumes.

04 Composition and actual final volume

Masses normally add in a closed, nonreacting preparation, but liquid volumes may change when components are mixed. A volume ratio therefore does not always determine the final concentration per measured final volume.

Scaling the arithmetic does not automatically preserve mixing time, heat transfer, solubility, or process performance. Treat the output as a quantity balance. The calculator does not decide whether the listed substances are chemically compatible or whether the formulation is suitable for a particular use.
