Dilution Calculator
Solve any one unknown in the dilution relation C1V1 = C2V2 and report concentration and volume ratios.
Formula
Initial concentration x initial volume = final concentration x final volume.
About the Dilution Calculator
Solve any one unknown in the dilution relation C1V1 = C2V2 and report concentration and volume ratios.
How the Dilution Calculator Works
The selected unknown is isolated algebraically while concentration units match each other and volume units match each other; no hidden unit conversion is applied.
Formula
Initial concentration x initial volume = final concentration x final volume.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Unknown quantity (required).
- Initial concentration C1 (optional).
- Stock volume V1 (optional).
- Final concentration C2 (optional).
- Final volume V2 (optional).

Accuracy and Limitations
The equation assumes additive volume and conserved solute. Use compatible concentration units, compatible volume units, and account for reactions, contraction, or density when relevant.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
