The specific surface area of an object is defined as its total actual surface area (including the deviations from ideal smoothness found in all materials) per unit of mass or volume. It is given in units of m2/kg or m2/g, or m2/m3 or m-1, depending on whether it is measured by mass or volume respectively.
