Default Tube weight to strength calculator (you may find this useful).

I am building a go-kart that calls for 1 1/8 x .083" wall tube, and I was having some trouble finding this specific material where I am located so I created this spreadsheet. It will calculate the deformation strength and pounds per foot for a given Outside Diameter and wall thickness of tube. I used these calculations to find a similar strength and weight tube for what I needed.

Please note however that you need to have a sufficient thickness of tube to prevent it from being dented. This calculation does not account for denting.

I got the calculations from this website.

I thought some of you may find this useful so here it is. The line that is highlighted is the baseline, you can set this to whatever you want and all the other values will be compared to it.

Here is the file.
