# HOW TO CALCULATE STEEL WEIGHT IN KG

### STEEL QUANTITY:

• Weight of bar in kg/meter should be calculated as (d2 ÷ 162) where‘d’ is the diameter of bar in mm.
• ‘L’ for column main steel in footing should be considered as minimum 30cm/as specified.
• For bent up bar add 0.42d in straight length of bar where‘d’ is the clear depth of beam/slab.
• For cantilever, beam anchorage length for main steel should be 69D or length of cantilever whichever is greater.

#### Weight per meter of different dia of steel bar.

• 6    = 0.222 kg per meter
• 8    = 0.395 kg per meter
• 10 = 0.617 kg per meter
• 12 = 0.888 kg per meter
• 16 = 1.58 kg per meter
• 20 = 2.469 kg per meter

With help of this formula you can find any type of dia bar weight

(d2 ÷ 162)

Where

D = diameter of bar in mm.

### Calculate number of stirrups in column or beam

• Number of Stirrups = (clear span/spacing) + 1
• Lap length in column should be 45D

Where

D = diameter of bar in mm

• Lap length in beam/slab should be 69D

Where

D = diameter of bar in mm
