Round Bar Weight Calculator (MS Round Bar Weight Calculator)

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
