Charts for Track Width Versus Current

Appendix D of Simon Monk’s Make Your Own PCBs includes a track width vs current chart. A note appearing below the chart indicates the original author of the chart unknown. The chart is not legible.

What is your intention with showing those charts?

Are you aware of KiCad’s built-in calculator tools?

Thanks Paul.

Again, we are trying to keep this forum on-topic on KiCad, not general electronics. If there’s something about KiCad’s calculator to ask, please ask, otherwise I’ll close this topic after a while.

A quick reference and visual aid.
