PPM & Dilution Calculator
Calculate stock quantity and diluent make-up using C₁V₁ = C₂V₂ on an explicitly consistent concentration basis.
This tool provides a preliminary engineering calculation for reference. Final equipment selection, design and commissioning decisions must consider manufacturer data, applicable standards, operating conditions and project-specific engineering requirements. It is not certified design output.

Calculated outputs
Enter values and select Calculate. Results are estimates and do not replace nameplate data, applicable standards, or an engineering review.
Use this calculation
Only calculator parameters and results are transferred. Personal details are collected separately in the destination form.
Formula
C₁V₁ = C₂V₂
V₁ = C₂V₂/C₁
Worked example
10000 ppm stock to make 100 L at 500 ppm.
Expected check: Stock quantity = 5.
Assumptions
- • C₁ and C₂ use the same concentration basis
- • Prepare to final volume rather than assuming exact additive volumes
Limitations
- • Does not interchange w/w, w/v, molarity and ppm without density or molecular-weight data
- • Chemical compatibility and safe handling are outside this calculation
Frequently asked questions
Can this result be used for final equipment selection?
No. Use it for a preliminary check, then verify manufacturer data, site conditions, applicable standards and the complete system design.
What does formula version 1.0.0 mean?
It identifies the exact calculation logic used so a saved result can be traced when the formula register changes.
Can Elexorn review my calculation?
Yes. Transfer the result to Request a Quote or Talk to an Elexorn Engineer and add the relevant project or equipment details.
