*SHEET*

WEIGHT (KGS) = LENGTH (MM) X WIDTH (MM) X 0. 00000785 X THICKNESS

example – The weight of MS Sheet of 1mm thickness and size 1250 MM X 2500 MM shall be

2500MM X 1250 MM X 0.00000785 X 1 = 24.53 KGS/ SHEET

**MS SQUARE**

WEIGHT (KGS ) = WIDTH X WIDTH X 0.00000785 X LENGTH.

Example : A Square of size 25mm and length 1 metre then the weight shall be.

25x25X 0.00000785 X 1000mm = 4.90 kgs/metre

**MS ROUND**

WEIGHT (KGS ) = 3.14 X 0.00000785 X ((diameter / 2)X( diameter / 2)) X LENGTH.

Example : A Round of 20mm diameter and length 1 metre then the weight shall be.

3.14 X 0.00000785 X ((20/2) X ( 20/2)) X 1000 mm = 2.46 kgs / metre
