Solution Mixtures Calculator - Units per Volume

Meant to be used in both the teaching and research laboratory, this calculator (see below) can be utilized to perform calculations for __solution mixtures__ (e.g., mixing two solutions) when working with solutions having __units per volume__ (i.e., units over volume) concentration units such as Units/mL, μUnits/μL, mUnits/mL, Units/L, etc. These calculations are commonly performed when working with enzymes and other biologically active molecules, where units of activity are defined based on the standard established for each molecule and its biochemical or biological function. For a description of when units of activity are used in biochemical and biological applications, please see our Dilution Calculator - Units per Volume. Additional solution mixtures calculators are also available and are suited to more specialized applications (see here).

If you wish to perform **dilution** calculations for solutions with units per volume concentration units, use our Dilution Calculator - Units per Volume. If you wish to perform **dilution factor** or **fold dilution** calculations for solutions with units per volume concentration units, use our Dilution Factor Calculator - Units per Volume.

Solution mixtures calculator - units per volume

The calculator below may be used when mixing two solutions, and when working with solutions having **units per volume** (i.e., units over volume) concentration units such as Units/mL, μUnits/μL, mUnits/mL, Units/L, etc. To use the calculator, enter appropriate values in all cells except the two cells you wish to calculate. For example, enter concentration and volume values for solution 1 and solution 2, and leave the concentration and volume for the solution mixture blank. *Therefore, at least four cells must have values, and no more than two cells may be blank*. The value of each blank cell will be calculated based on the other values entered. After a calculation is performed, the calculated cell will be highlighted and subsequent calculations will calculate the value of the highlighted cell (with no requirement to have a blank cell). However, a blank cell has priority over a highlighted cell.

As noted above, at least two parameters must be left blank. Additionally, it is important to note that **no two concentrations can be calculated at the same time**. Therefore, the following calculation combinations are not allowed: (Concentration 1 and Concentration 2), (Concentration 1 and Mixture Concentration), and (Concentration 2 and Mixture Concentration). All other calculation combinations are allowed.

For convenience, this calculator allows you to select different volume and concentration units, and the necessary conversions are carried out for you to obtain the value of the blank cell in the desired unit.
