Permittivity of vacuum unit
Web2. jan 2006 · In SI units, the vacuum permittivity is defined to have an exact value of ε 0 = 1/(μ 0 c 2), where μ 0 is the magnetic permeability of free space and c stands for the speed of light in vacuum. This has the approximate numerical value ε 0 ≅ (8.854 187 817)*10-12 F/m. In more familiar units, F/m = C 2 /(N m 2).
