Good Question. All Tube is measured by its OD (Outside Diameter) and is manufactured in Imperial Sizes (2", 3" etc) EXCEPT wall thickness is in millimetres (1.6mm / 2.0mm etc)

Since we live in a metric world we convert the Imperial sizes to metric and sometimes we call 3" 76mm for easy rather than saying 76.2mm (and the same for other sizes).

Here is a chart that converts inches to millimetres
