### Units of measurement of potential energy

Potential energy formula is $$PE=\frac{kq1q2}{r}$$where $$k=\frac{8.99e9J*m}{C^2}$$ How is this k value derived? What is $$\frac{J*m}{C^2}?$$
Any science consists of the following process. 1) See 2)Hear 3)Smell,if needed 4)Taste, if needed 5)Think 6)Understand 7)Inference 8)Take decision [Believe or disbelieve, useful or useless, true or false, cause or effect, any other criteria]

### Re: Units of measurement of potential energy

C = Coulomb = As

Energy Pe has unit J = Joule

So if Pe = k* q1*q2/ r then k = Pe*r/q1*q2 in unit J * m/(As)^2 = J*m/C^2
