Frequently Asked Questions
Everything you need to know about the Dilution Calculator.
How does the dilution calculator work?
Enter any 3 of concentration/volume before and after dilution; it solves C1V1=C2V2 for the missing value.
Is it free?
Completely free, no sign-up, downloads, or limits.
What units are supported?
Common concentration units (M, mM, µM, %, mg/mL) and volume units (L, mL, µL), with automatic conversion.
Can it handle serial dilutions?
Yes, enter a starting concentration, dilution factor, and number of steps to get a full concentration table.
Does it tell me how much diluent to add?
Yes, it explicitly computes and shows the volume of diluent needed to reach your target.
Does it show the steps?
Yes, the rearranged formula with your actual numbers substituted is shown, plus the full table for serial dilutions.
Can I mix units, like starting in mM and ending in M?
Yes, units are automatically converted before solving.
What if I enter invalid values?
Non-numeric, zero, or negative values are flagged with a clear message.
Is my data stored?
No; everything runs in your browser and isn't stored or sent anywhere.
Does it work on mobile?
Yes, fully responsive on all screen sizes.
