Dilution Calculator (C₁V₁ = C₂V₂)

Pick which quantity you need, enter the other three, and get an exact result from the dilution equation: C₁V₁ = C₂V₂.

Solve for:

Initial Concentration (C₁) (mol/L)*

Initial Volume (V₁) (mL)*

Final Concentration (C₂) (mol/L)*

FAQs

Do the units need to be exact (mol/L, mL)?

No — concentration just needs to use the same unit on both sides, and volume the same unit on both sides, since the equation is a straightforward ratio. The labels default to mol/L and mL as the most common lab units.
