The Loschmidt constant is exactly 1 amagat.
2006 CODATA value is 2.6867774(47) * 10^25 m^-3.
2010 CODATA value is 2.6867805(24) * 10^25 m^-3.
Measured at 0 degrees C and 1 atm (273.15 K, 101.325 kPa).
From Jianing Song, Jul 06 2019:
Equals (p_0)/(k*T_0), where p_0 = A213611 = 101325 Pa is the standard pressure, k = A070063 = 1.380649*10^(-23) J/K is the Boltzmann constant and T_0 = 273.15 K is the standard temperature. In the May 20 2019 redefinition of the SI base units k is fixed to an exact value, so n_0 is also fixed to an exact value.
Equals (p_0*N_A)/(R*T_0), where N_A = A322578 is the Avogadro constant, R = A070064 is the molar gas constant.
As this constant can also be represented as 6755/2514161829 * 10^32 (see below), this sequence is purely periodic with period 1910112. (End)
