Weight of Tempered Glass

Hi Mike,
The density of tempered glass is exactly the same as raw glass which is approximately 2270 kg/m^3 (2.27 kg/m^2/mm)
I assume you are in the USA, as you are asking about 3/8" glass, so the conversion is approximately 0.5 lbs/ft^2/mm which gives:
4.7625 lbs/ft^2 for 3/8" glass.
Be aware that even though you have ordered 3/8 glass, the float-line may give you something just under 3/8". (It improves their profit margin!)
Regards,
Jonathan Barr

My question is along the lines of the original. Is there a chart somewhere with the lbs per square foot or lbs per square inch for the different size thickness glass? The two sizes that I am looking for is 3/16 and 1/4 tempered? I would imagine that there is no difference between tempered and regular pane glass weight?

Any help would be greatly appreciated!


Thanks
JJ

A quick rule of thumb for glass weights (metric) is
2.5Kg/sqm per mm of glass thickness
ie 3.3sqm of 8mm glass weighs:
3.3 x 8 x 2.5 = 66Kg
In USA use 13.2lbs per sq ft per inch of thickness, ie 12sq ft of ½" glass:
12 x 0.5 (ie ½ ) x 13.2 = 79.2lbs, give or take an ounce

To answer JJ's question, the rough numbers are here:
3/16": 2.55 lb/sqft, 1/4": 3.07 lb/sqft. The weight should be similar for anneal and tempered glass. Help this answers your question. If you need more help, please contact.

The weight of the glass if it is being used as a coffee table will depend on the weight of your "chick" sitting on it plus pie 'r' squared *laughs*...sorry, just having some fun.

Thanks, to everyone that replied that definately helps me out, even the reply from newbie (always enjoy good laugh). I can not tell how long I have been perusing the internet to find these answers. I indirectly was close to the lbs per square inch on the 1/4 glass from information that I found.

Again, Thanks!
JJ

Well I just signed up for this website, so Im sure you already got your answer. But ....
3/16" = 2.51 pound per sqaure foot
1/4" = 3.28 " "

tempered and annealed are the same in weight
