The d×d/162 formula

Steel weighs about 7,850 kg per cubic metre, so a round bar of diameter d mm weighs d × d ÷ 162 kg per metre (12 mm → 0.889 kg/m). The weight on the bill may differ a little — bars are rolled to a tolerance. Your engineer’s bar bending schedule gives the lengths, laps and number of bars.

Kaise use karein

  1. Sariya ka diameter, lambai aur ginti bharein.
  2. Har diameter ka kg aur kul tonne dekhein.
  3. Rate bharkar kharcha dekhein; PDF download karein.

Questions people ask

How do I calculate steel weight?
Weight per metre = d × d ÷ 162 (d in mm). Multiply by the total length. For example 10 bars of 12 mm, 12 m each = 120 m × 0.889 = 106.7 kg.
How many 12 m bars?
Total length ÷ 12, rounded up — the page shows it for each diameter (change the bar length if yours are sold in another length).
Is my data uploaded?
No. Everything is worked out in your browser and the PDF is made on your device.
