The fine-structure constant remained mysterious and perplexing for many years until Dan Cleary, from Kemptville Ontario Canada, discovered that it is the conversion ratio from elementary charge (e²) to Planck charge (q_p²).

Alpha's definition is:

a=e²/4pi epsilon_0 hbar c

Planck charge definition is:

q_p²=4pi epsilon_0 hbar c

So

a=e²/q_p²

It indicates that you've used the wrong charge.

In [[physics]], the '''fine-structure constant''', also known as the '''Sommerfeld constant''', commonly denoted by {{mvar|α}} (the [[Alpha|Greek letter ''alpha'']]), is a [[Dimensionless physical constant|fundamental physical constant]] that quantifies the strength of the [[electromagnetic interaction]] between elementary charged particles.
