The 28,27 in the picture
-
What part is confusing? The only parameter that was a little unusual was the 28.27 square mm copper area of the tubing. I believe that this means the cross sectional area of the copper. I have never seen anyone use this spec before.

Yes that was it, don't use metric that much is why it looked strange. Thank for the info, now I can sleep.

The 28,27 in the picture
I wrote it :)
It is the cross section in square millimeters, in order to put the correct "wire size" into calculators for primary coil calculations. JavaTC asks for a wire gauge, but if you enter the total cross section of the outer diameter, you would get a erroneous result.
For the same reason to avoid confusion, I added both the European and American wire gauge tables into one: http://kaizerpowerelectronics.dk/theory/wire-size-table/

I think I know what's going on here, some countries use a comma to separate fractions of a millimeter whilst others use a dot so 28,27mm doesn't register as 28.27mm to dot using folk (took me a few seconds for it to click). At first 28,27 reads as two thousand eight hundred and twenty seven.

You are right. I am from comma country and I do try to write all my stuff as dot separator, as I do write in English and the dot is used in the native english speaking countries :)

Funny how a few extra pixels mean different things around the world! Are there any things native English people write online which look funny to places where English isn't the first language?
