Total Weight = 14.79 kg
Round bar dimension: D = Diameter
Formula Used to Calculate Round Bar Weight
The weight of a round steel bar can be calculated using the following formula:
Weight (kg) = D² × 0.006165 × Length
- D = Diameter of round bar in millimeters
- Length = Bar length in meters
- 0.006165 = Constant derived from steel density
Example Calculation
For a round bar with the following dimensions:
- Diameter = 20 mm
- Length = 6 meters
Weight = 20² × 0.006165 × 6
Total Weight ≈ 14.79 kg
