COMMENTS

Since the conventional volt (i.e., V_{90}, as stated in A361006) is the electromotive force measured against a Josephson effect standard using the defined value of the Josephson constant, K_{J90}, and given the fact that the conventional ohm (i.e., Omega_{90}, as stated in A361010) is the electrical resistance measured against a quantum Hall effect standard using the defined value of the von Klitzing constant, R_{K90} (see Wikipedia, "Conventional electrical unit", in Links), it follows that the conventional watt (i.e., W_{90}) is given by A_{90}*V_{90}, which is (K_{J90}/K_J)^2*(R_{K90}/R_K) according to the 2019 SI system in units W.

FORMULA

W_{90} = ((483597.9*10^9/((2*1.602176634*10^(19))/(6.62607015*10^(34))))^2)*((25812.807)/((6.62607015*10^(34))/(1.602176634*10^(19))^2)) = 1 + 15642924386799194873461/80000000000000000000000000000 W.
