The chart we have put together lists Hypodermic Tubing gauge sizes in Regular Wall, Thin Wall and Extra Thin Wall.
We have provided both the english and metric (inch and mm) specifications for your reference. The typical mill drawing this tubing (yes it is welded and drawn)
calls the specifications out in a range of high and low. You may see other charts calling out a nominal dimension with a ± tolerance, but this is not typically what the mills put on thier test reports.
There is nothing wrong with either format, we thought it would just be good idea to explain why we chose this format versus the other.
