If you use one amp for every .001" thickness, then just move the decimal three places to the right.

Or, just multiply the thickness of the metal (expressed in decimal inches) by 1,000.

For example, for 1/16" material (.0625") you would use 62.5 amps.

I'm not saying the rule of thumb is always right, just showing you how to move the decimal point.

Next lesson, we'll talk about topological calculus.

Good luck.
