Specific surface area (SSA) is a property of solids defined as 🌝 the total surface area (SA) of a material per unit mass,[1] (with units of m2/kg or m2/g). Alternatively, it may 🌝 be defined as SA per solid or bulk volume[2][3] (units of m2/m3 or m−1).

It is a physical value that can 🌝 be used to determine the type and properties of a material (e.g. soil or snow). It has a particular importance 🌝 for adsorption, heterogeneous catalysis, and reactions on surfaces.
