Enter the initial volume and the dilution volume into the calculator below to determine the final volume and the dilution factor. The dilution factor is a ratio of dilutant to total stock or volume.
Dilution Factor Formula
The following equation can be used to calculate the dilution factor.
D:S = D / S
- Where D:S is the dilutant to stock volume ratio
- D is the volume of dilutant
- S is the volume of the stock (also known as the total volume)
As with all ratios, the formula for calculating that ratio is a simple division. It’s important to remember that the units should be the same for the volume of the dilution and the final volume. Otherwise you will not get the correct ratio.
