The conventional volt (i.e., V_{90}) is the electromotive force measured against a Josephson effect standard using the defined value of the Josephson constant, K_{J-90} (i.e., 483597.9 GHz/V). Hence, K_J = 483597.9 GHz/V_{90} (see Wikipedia, "Conventional electrical unit", in Links).
Thus, according to the 2019 SI system, V_{90} is given by K_{J-90}/K_J in units V.

FORMULA
|
V_{90} = K_{J-90}/K_J = 483597.9/((2 * 1.602176634*10^(-19))/(6.62607015*10^(-34))) = 71207857995393/71207850400000000000000 V.
