I am trying to figure out the thickness of a metal bar in my glass cabinet. I need to find the thickness as I need to get some plastic tubing to cover them.
Can someone that knows the way to work this out please help me ?.
I have took a piece of paper and wrapped it around the bar once and then measured that - 2cm. I need to know what that equates to and if tubing listed as having either - 3mm/8mm/12mm inside diameter would fit around the bar once its cut. I want the tubing to cover some think cabling as well. This is a project to put lighting in around the support bars.
Its hard to explain. I just cant get my head around it. I was good at most other things in math but not the diameter side of things.
