Comments

Since the Boltzmann constant k in the 2019 SI system is equal to 1.380649×10^(-23) J/K (see A070063) and given the fact that c = 299792458 m/s is also exact according to the same system (see A003678), it follows that k/c^2 is a rational number.

For the (inverse) kilogram/kelvin relationship in kelvin units, c^2/k = 6.509657260...*10^39 K, see links.

Formula

a(n) = A070063 / A003678^2.

k/c^2 = (1.380649*10^(-23))/299792458^2 = 18913/123117147772166800000000000000000000000000000 kg.

Example

1.536179187240372234762...*10^(-40) (rational number).
