๐งซ Dilution Calculator (C1V1=C2V2)
Leave only the one value you want to solve for blank, and enter the other three.
Use the widely-used dilution formula "C1V1 = C2V2" (initial concentration ร initial volume = final concentration ร final volume) to solve for whichever one of the four values you leave blank, given the other three. Units follow whatever you enter, so use a consistent unit system throughout.
How to use
- Leave blank whichever one of the four values (C1, V1, C2, V2) you want to calculate.
- Enter the other three values.
- The blank value is calculated automatically.
FAQ
What does C1V1=C2V2 mean?
It expresses conservation of the total amount of solute (moles or mass) during dilution: initial concentration ร initial volume (C1V1) equals final concentration ร final volume (C2V2).
What units should I use?
Use a consistent unit for concentration (C1, C2) and a consistent unit for volume (V1, V2) โ e.g. concentration in mol/L or %, volume in mL or L. Mixing units will give an incorrect result.
What if two or more values are left blank?
This tool can only solve when exactly one of the four values is left blank. No result is shown if two or more are blank.
