%N Decimal expansion of conventional value of ampere-90 (A_{90}).
%C The conventional ampere (i.e., A_{90}) is given by V_{90}/Omega_{90}, which is (K_{J-90} * R_{K-90})/(K_J * R_K) according to the 2019 SI system in units A.
%C Moreover, according to the 2019 SI system, also the conventional value of coulomb_90 (C_{90}) is given by the present sequence in units C (i.e., C_{90} = 1.00000008887143810491801 A*s).
