About this app

Lab Calculator is a lightweight science calculator for common solution concentration work in class, lab preparation, and research routines.

Switch between percent concentration, molarity, dilution, and ppm/ppb tools. Enter the known values, choose units, and calculate the missing value without setting up a spreadsheet.

Key features

- Percent concentration: calculate %, solute mass, or solution volume
- Molar concentration: calculate concentration, molecular weight, mass, or volume
- Dilution calculator: based on C1 x V1 = C2 x V2
- ppm/ppb calculator: trace concentration using mg/L
- Unit selection: g, mg, μg, L, ml, μl, M, mM, μM, and more
- Quick reset: clear inputs and start a new calculation
- Compact layout: designed for fast use on small screens

Useful for

- Students preparing chemistry experiments
- Researchers working with stock and working solutions
- Users who often check percent concentration, dilution, or ppm values
- Anyone who wants a simple calculator instead of a spreadsheet

No account is required. Values entered for calculation are not sent to a server.
