Plate Steel Weight Question

Does anyone here happen to know about how much a square foot of 1/2" plate steel weighs?

 

20.376 lbs.

Formula : length X width X thickness X .283 = weight of steel.

or

area X thickness X .283 = weight

 

here's a good reference website:

ME steel

 

Thanks Boss.

 

Remember what Johnyfast said the easy way. A CUBIC INCH of steel is a SBC {.283} pounds.
