Iron Flat Bar Weight Calculator

Summary

Enter width, thickness, and length of an iron flat bar to instantly calculate its weight using iron density (7.87 g/cm³).

How it works

1. Select your preferred unit system: metric (mm / m) or imperial (in / ft).
2. Enter the flat bar width in millimeters or inches.
3. Enter the flat bar thickness in millimeters or inches.
4. Enter the total length in meters or feet.
5. Optionally enter a quantity to compute total weight for multiple bars.
6. The calculator applies Weight = Width × Thickness × Length × 7.87 g/cm³ to produce results in kg and lb.

Use cases

• Estimate iron flat bar weight before placing a material order.
• Calculate structural dead load for iron bar components.
• Determine freight weight for shipping cost estimation.
• Compare mass across different flat bar sizes during design.
• Quickly verify weight budgets on fabrication projects.
• Convert between kg and lb for cross-region specifications.
• Check material quantities against a bill of materials.
• Plan lifting and handling requirements on the job site.
