This unit 'ounces of copper', does it apply to 1)square foot ? 2)square yard ? 3)square meter ? European thicknesses are 35, 70, 105, 150, 200 and 300 micrometer. I just wondered how they relate. One ounce is 28 grams, isn't it ? Rene Stephen Smith wrote: Does anyone know a simple way of

Does anyone know a simple way of calculating copper track size (in, mm), when you know the amount of copper (in, ounces), and the current flow (in, Amps)?? I've never had to do any high current circuits before, so any help much appreciated. Steve * * * * * * * * * * * * * * * * * * * * * * * *
