statvolts top-level property
A useful unit for electromagnetism because, in a vacuum, an electric field of one statvolt/cm has the same energy density as a magnetic field of one gauss. Likewise, a plane wave propagating in a vacuum has perpendicular electric and magnetic fields such that for every gauss of magnetic field intensity there is one statvolt/cm of electric field intensity.
