Comments

The conventional ohm, Omega_{90}, is the electrical resistance measured against a quantum Hall effect standard using the defined value of the von Klitzing constant, R_{K-90} (i.e., 25812.807 ohm).

Hence R_K = 25812.807 * Omega_{90} in units ohm (see Wikipedia, "Conventional electrical unit", in Links).

Thus according to the 2019 SI system, Omega_{90} is given by R_K/R_{K-90} in units ohm.

Moreover, according to the 2019 SI system, also the conventional value of henry_90 (H_{90}) is given by the present sequence in units H (i.e., H_{90} = 1.00000001779366756432361334 kg*m^2*s^(-2)*A^(-2)).

Formula

Omega_{90} = R_K/R_{K-90} = (6.62607015*10^(-34)/(1.602176634*10^(-19))^2)/25812.807 = 1 + 98251739507564459/5521725026748260492435541 ohm.
