Solution Preparation & Dilution Tools
Make stock and working solutions, convert concentration units, and plan dilution series — all in your browser.
These calculators cover the everyday bench path from weighing out a solid to holding a working solution: molarity from mass and volume, C1V1 = C2V2 dilution, percent solutions (w/v and v/v), multi-step serial dilutions, and conversion between mass-based (mg/mL) and molar (mM, µM) concentration units. Everything runs client-side, so nothing you type leaves your device.
Molarity & Solution Preparation Calculator
Solve for molarity, solute mass, or solution volume from the other two values.
Open tool →Dilution Calculator
Calculate dilution using the C1V1 = C2V2 formula. Solve for any variable.
Open tool →Percent Solution Calculator
Calculate percent concentration (w/w, w/v, v/v) of a solution.
Open tool →Concentration Converter
Convert between mg/mL and mM (molar concentration) using molar mass.
Open tool →Serial Dilution Calculator
Calculate concentration at each step of a serial dilution. Supports dilution factor and step count, with optional per-step volume.
Open tool →Solubility Converter
Convert solubility units between g/L, mg/mL, mol/L, ppm and more, with mass-to-molar conversion by molecular weight.
