## Quick Answer

Calculate dilution concentrations or volumes using the M1V1 = M2V2 formula. Enter any three variables to solve for the fourth.

## Definition

Dilution is the process of reducing the concentration of a solute in a solution, usually by mixing it with more solvent. A dilution calculator computes the relationship between the concentrations and volumes of two solutions using the formula M1V1 = M2V2. By inputting three of the variables, the calculator solves for the missing parameter and determines the dilution factor. Laboratory researchers, pharmacists, and chemistry students use this tool to prepare standard solutions from concentrated stock solutions.

## How to Use

1. **Choose variable to solve** — Select which concentration or volume parameter you need to calculate.
2. **Input known values** — Enter the concentration and volume values for your stock and diluted solutions.
3. **Read dilution instructions** — View the calculated result and the step-by-step guide on how much solvent to add.
