# HOW TO CALCULATE STEEL WEIGHT IN KG

__STEEL QUANTITY:__

__STEEL QUANTITY:__

- Weight of bar in kg/meter should be calculated as
**(d**^{2 }**÷ 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

**(d ^{2 }**

**÷ 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
