I have always held (and still do I suppose) the view that gravity is much weaker than the coulomb electrical force due to the fact the equations are so similar you can just compare the constants from each equation showing that the graviational force is many orders of magnitude smaller. However, I stumbled across this article:

What are peoples views on this? Is everything outlined in this true? It seems to say that since Newton's Gravitational constant is not dimensionless you can't compare the strengths as I outlined at the start of this thread? I kind of get the point they are making because you could come up with a compatible equation for gravity with different units that makes the constant of proportionality much bigger. However, I thought that since both equations use Newton's and square meters they are directly comparable?

Thanks!
