AppSolute (Pro) is the concentration unit converter. It can convert 19 units,

- Molar (Mole of solute per Liter of solution): mol/L
- Molal (Mole of solute per Kilogram of solvent): mol/kg
- Milliequivalent of solute per Liter of solution: mEq/L
- Ratio of weight and volume
1. Weight by weight (Weight of solute per weight of solution): w/w
2. Weight by volume (Weight of solute per volume of solution): w/v in g/ml (gram per milliliter) and g/L (gram per liter)
3. Volume by volume (Volume of solute per volume of solution): v/v
- Percent (%) of w/w, g/ml, v/v: %w/w, %g/ml, %v/v
- Part per million (ppm) of w/w, g/ml, v/v
- Part per billion (ppb) of w/w, g/ml, v/v
- Part per trillion (ppt) of w/w, g/ml, v/v
4. Imperial and United state units: e.g. lb/gallon, oz/cu.in, oz/fluid oz

Also, it can receive and display the output in number, decimal, scientific notation, fraction, mixed number, repeating number.
