Once the units are known, various waters can be quantitatively described. The units of measurement used to describe conductivity and resistivity are quite fundamental and are frequently misused. Once the units are known, various waters can be quantitatively described. - The basic unit of resistance is Ohm. Conductance is the reciprocal of resistance and its basic unit is Siemens (S). In discussions of bulk material, it is convenient to talk of its specific conductance,​ now commonly called its conductivity. This is the conductance as measured between the opposite faces of a 1 cm cube of the material. This measurement is taken in units of S/cm. The units //mS/cm// (milliSiemens per cm) and //µS/cm// (microSiemens per cm) are most commonly used to describe the conductivity of aqueous solutions. The corresponding terms for specific resistance (or resistivity) are //Ω.cm//, //MΩ.cm// and //kΩ.cm//. + The basic unit of resistance is Ohm.
