COMMENTS

Also, decimal expansion of the ratio between energy and mass measured in meter^2/second^2. By Einstein's formula E/m = c^2.
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.
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
Also Coulomb's constant (electrostatic constant).  Jim Singh, Sep 27 2018
