Why is the smaller the AWG number and the larger the diameter? Provide your American AWG, inch SWG wire gauge diameter comparison table

I believe that many engineers sometimes find it very troublesome for the British inch inch and the US system. I also use this conversion table often, so I will share it with you! I hope to help everyone. We are experts in wire production, and we can learn from each other if we have any questions.
