Flat Bar Weight Calculator (MS Flat Weight Calculator)

Formula Used to Calculate Flat Bar Weight

The weight of a mild steel flat bar can be calculated using the following formula:

Weight (kg) = Width × Thickness × Length × 7.85 / 1,000,000

• Width = Flat bar width in millimeters
• Thickness = Flat bar thickness in millimeters
• Length = Flat bar length in millimeters
• 7.85 = Density of mild steel (g/cm³)

Example Calculation

If a flat bar has the following dimensions:

• Width = 50 mm
• Thickness = 6 mm
• Length = 6000 mm

Weight = 50 × 6 × 6000 × 7.85 / 1,000,000

Total Weight = 14.13 kg

Frequently Asked Questions

What is the density of mild steel?

The density of mild steel is approximately 7850 kg/m³ or 7.85 g/cm³.

Why is flat bar weight calculation important?

Flat bar weight helps engineers estimate material cost, transportation weight, and structural load calculations in fabrication and construction projects.
