Molarity Calcs vs Fast Molality Calculator

Calculate mass to add to a volume, volume to add to a mass, or make a dilution. Fast.

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.
