SSA = S / m
Spherical estimate: SSA approx 6 / (ρ x d)
BET: gas adsorption is used to estimate monolayer surface coverage.

Example: if S = 12 m2 and m = 4 g, SSA = 12 / 4 = 3 m2/g.
Luu y quan trong: BET values are laboratory measurements. Geometric formulas are only rough estimates for non-porous particles.

Use Sphere, Ellipsoid, unit conversion, and surface area vs volume.
