COMMENTS
Before the redefinition of the SI units this value is A182999 with offset 10. After redefinition the value of the Coulomb constant is (8987551792.3 +- 1.4) kg*m^3*s^(-4)*A^(-2).
The Coulomb constant k can be expressed in basic constants as k = (alpha * h * c)/(2*Pi * e^2), where alpha (A003673) is the fine-structure constant, h (A003676) is the Planck constant, c (A003678) is the speed of light, and e (A081823) is the elementary charge. The constants h, c, and e are defined to be exact, so the relative precision of the Coulomb constant is the same as that of the fine-structure constant.
