Guides size in mm or inch

Guide equivalency size mm / inch

This guide in table form allows you to find very quickly the equivalences between the dimensions of a flattened measured tubing and its size expressed in diameter (useful inner dimension)
Practical reminder if the piece you are looking to cover is not round, just measure its perimeter in mm and divide by 3.14, so you will have the diameter in mm.
The sizes are also available in inch "
