How many tons does a 20mm rod make?
Mathematical calculation such as number of pieces of 20mm Rods in one ton = 1000kg/weight of one piece of 20mm Rod, 1000kg ÷ 29.63kg = 34 pieces. Therefore 34 No’s of 12 meter of 20mm Rod or steel bar makes a ton.
How is dia of steel bar calculated?
Example 1: Let’s assume the dia of a bar is 12 mm. So, the weight of bar will be = (122 ÷ 162) = 0.888 kg/m.
Weight of Steel bar Per Meter Length for Different Dia of Bar.
| Dia of bar | Calculation | Weight per meter |
|---|---|---|
| 25 mm | (252 ÷ 162) | 3.858 kg/m |
| 28 mm | (282 ÷ 162) | 4.839 kg/m |
| 32 mm | (322 ÷ 162) | 6.32 kg/m |
| 36 mm | (362 ÷ 162) | 8 kg/m |
What is mass of 10mm dia of steel bar per meter?
If dia of steel = 10mm, length of steel rods = 1 meter, then weight of 10mm steel rod per meter = (10×10×1)/162 = 0.617 kgs, so 10mm Steel rod weight per metre is 0.617 kgs. Ans. 0.617 Kgs is weight of 10mm Steel rod per metre.
