The shop I bought the radius dish from had everything in millimeters. So I assume it's trade standard in Europe? Also, in engineering you have everything in millimeters, no matter how big (outside the US).

No, that's not the issue, I thought it was a typo. A 3 meter radius for the back... im not sure what you mean but it sounds way too large for a guitar, whatever the measurement is for.

He means the amount the back bulges out instead of being a flat plane. The arc of it is curved the same amount as a segment of a circle with a 3 meter radius. The bigger the radius, the less the back curves.

Think a situation like this, except with a smaller surface area:

It's being bent. The wood won't cover the entire circle, only some small arc segment, by my understanding. A smaller radius would be a much more dramatic bend (and probably break)
