Dilution Ratio Calculator

The dilution ratio is the ratio of the solute (the substance to be diluted) to the solvent (e.g., water).The diluted liquid needs to be thoroughly mixed to achieve true dilution. If you have a 1:3 dilution, i.e. a 1:3 dilution ratio, this means that you add 1 unit volume of solute (e.g., concentrate) to 3 unit volumes of the solvent (e.g., water), which will give a total of 4 units of volume.
