Symbol:	α_v γ
Definition:	quantity characterizing the variation with thermodynamic temperature T of the volume V of a body, under given conditions, thus $α_{V} = \frac{1}{V} \frac{d V}{d T}$ NOTE 1 When relevant, e.g. for a gas, the pressure should be given. NOTE 2 The coherent SI unit of cubic expansion coefficient is kelvin to the power minus one, K⁻¹.
