### Dimensional Analysis in Electromagnetism (SI vs Gaussian-cgs)

Here's the conversion. I will write Gaussian quantities as $$\hat{φ}, 𝐚, 𝐛, 𝐞, 𝐝, 𝐡, 𝐣, \hat{ρ}, q, \hat{ε}, \hat{μ}$$ and the corresponding SI quantities as φ, 𝐀, 𝐁, 𝐄, 𝐃, 𝐇, 𝐉, ρ, e, ε,...

### Why can the Ampere not be defined as the flow of $n$ Coulomb in $n$ seconds?

Mathematically , both are Equivalent. Practically , we might have Difficulties. There at least 3 Issues or flaws with your way. (1) When we say "n" , we are leaving it unknown. When I report ...

### Why can the Ampere not be defined as the flow of $n$ Coulomb in $n$ seconds?

That’s how it is defined, using the 1’s rather than the n’s. You’re not really missing anything about the math/physics of the situation. Yes your definition would indeed give the same result. It’s ...
