Solution Dilution Calculator (C1V1=C2V2)

Enter three known values (e.g., C1, V1, C2) and leave the unknown empty. The tool will solve it instantly.

Initial concentration (C1):

Initial volume (V1), mL:

Final concentration (C2):

Final volume (V2), mL:

Enter exactly three values; leave the one to compute empty.

The dilution equation is C1×V1=C2×V2, where C is concentration and V is volume.

Use any units (e.g., %, mg/mL) but keep them consistent for C1 and C2. Volumes are in mL.

Making weaker solutions from stronger stock, preparing standards, and adjusting sample concentrations.
