What Is a Dilution Factor Calculator?

Dilution factor describes how much a stock solution has been diluted — expressed either as a ratio (like 1:10) or as a 'fold' value. This calculator finds both forms from the volume of stock solution used and the final total volume.

How to Use This Dilution Factor Calculator

  1. Enter the volume of stock (concentrated) solution used.
  2. Enter the final total volume after dilution.
  3. Click Calculate to get the dilution factor and fold-dilution.

Formula

Worked Example

1 mL of stock solution is diluted up to a final volume of 100 mL. Dilution Factor = 1:100, meaning a 100-fold dilution.

Frequently Asked Questions

What is a dilution factor?

It's the ratio of final volume to the volume of the original concentrated solution, often written like 1:10, meaning one part solute to nine parts diluent.

How is dilution factor calculated?

Dilution factor = final volume ÷ initial (aliquot) volume.

How is dilution factor different from concentration?

Dilution factor describes the dilution ratio itself, while concentration describes the resulting strength of the solution — they're related but not the same number.
