Feb 20, 2021 · Enterprise value (EV) is a measure of a company's total value, often used as a comprehensive alternative to equity market capitalization. EV includes in its calculation the market capitalization When used as a unit of energy, the numerical value of 1 eV in joules (symbol J) is equivalent to the numerical value of the charge of an electron in coulombs (symbol C). Under the 2019 redefinition of the SI base units, this sets 1 eV equal to the exact value 1.602 176 634 × 10 −19 J.
