Why gravitational constant $G$ does not have the factor of $4π$?
We know that electrostatic constant $K=\frac{1}{4\pi\epsilon}$.
This $4\pi$ came from the surface area of the surface in which charge is enclosed.
Then, why don't gravitational constant has the factor ...

Why is the constant in Coulomb's law written in terms of $\pi$ but not the constant in Gravitation?
What is the significance of writing it as $\frac{1}{4\pi \epsilon _0}$? Why not just name the whole thing $\epsilon _0$? And if there is a significance, why not do the same thing for gravitation?
I ...
