Dilution Factor: 1 mL into 100 mL
Taking 1 mL and diluting to a final volume of 100 mL gives a dilution factor of 100.
How to use this tool
- Enter aliquot volume (sample taken) and final volume after dilution in the fields above.

- Read your dilution factor (df) and the full breakdown beneath it.
A 1-in-100 dilution, frequently used in microbiology plate counts, yields a dilution factor of 100.
Frequently asked questions
- How is this different from the C₁V₁ dilution calculator?
- C₁V₁ = C₂V₂ calculates concentrations. The dilution factor calculator focuses on the volumetric ratio used in serial dilutions, microbiology, and spectroscopy where you track fold-dilution rather than absolute molarity.
- What is a serial dilution?
- Repeated dilutions where each step uses the previous diluted solution as input. Three 1:10 dilutions gives 1:1000 overall (DF = 1000).
