Comments

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.

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).

Formula

A_{90} = ((483597.9*10^9)*(25812.807))/((2*1.602176634*10^(-19))/(6.62607015*10^(-34))*((6.62607015*10^(-34))/(1.602176634*10^(-19))^2)) = 1 + 8887143810491801/100000000000000000000000 A.

Example

1.00000008887143810491801 (rational number).
