%N Decimal expansion of c^2, c being the speed of light in vacuum in SI units.

%C Also, decimal expansion of the ratio between energy and mass measured in meter^2/second^2. By Einstein's formula E/m = c^2.

%C This is a function of an assigned metrological constant. Regarding these, see A003678 for general context notes, references and links. - _Stanislav Sykora_, Jun 16 2012.

%C Also the upper limit on specific strength (ratio of strength to density) for any material in N*m/kg. - _Charles R Greathouse IV_, Apr 22 2016

%C Also Coulomb's constant (electrostatic constant). - _Jim Singh_, Sep 27 2018
