Okay, I made the file smaller, so I could upload it. You can put your own title on it.

Thanks for the work. I made a few copies for the study, shop, etc...

according to the charts, our modern cars are 1/32" thick skin...(.22ga.) I don't think the older cars were 18 ga. as stated , I was told the 50 ish cars were 20ga... anyway 1/32" sounds scary.....

I was needing this info about 2 weeks ago,I printed 1 out and saved it on my computer for future copies

[Taiden]

anyone else find it interesting that a square foot of 1/2" thick steel is EXACTLY 20.00 lbs?

Pretty cool!

i've been using one of these for a long, long time.

if you can work with fractions and you know that steel is app 40 lbs per ft sq, then it is pretty easy to convert to whatever you are dealing with.

ie .125/1/8th is equal to 5lbs per ft sq

.062/1/16th us equal to half of that.

after a while you can do them in your head. at least you can ball park a weight this way.

Thanks FDC. That got me to thinking since I'm making a table base out of 1" square tube.

A 3 foot length of 11 gauge (1/8") mild steel would also be 5 pounds, because it's 144 in2 (one square foot).

And since 16 gauge is half as thick, a 3 foot length would be 2.5 pounds.

And a 22 guage would weight half as much again - 1.25 pounds.

Very helpful now that I've got it in my head.

Thanks. This is really good to know, especially the weight per square foot.
