Density of steel in Cft = 490 Lbs/ Cft or 222.32 kgs/Cft
Volume = L x W x H = Cft
Let’s take an example,
if you want to calculate weight of a plate 1' x 1' x 1/2"
first calculate Volume
Volume = 1 'x 1' x 0.042' = 0.042 Cft
Now if you want to calculate weight in Lbs volume x 490
0.042 x 490 = 20.58 Lbs
or if you want to calculate weight in Kgs volume x 222.32
0.042 x 222.32 = 9.34 Kgs
you can convert lbs to kgs
20.58/2.204 or 20.58 x 0.454
