Calculation Steps
Our structural angle weight calculator follows these precise steps to determine the weight of your angle profile:
Weight = Density × Volume
Volume = (Leg1 + Leg2 - Thickness) × Thickness × Length
Volume = (A + B - t) × t × L
- Input Validation: The calculator first validates all input parameters to ensure they are within acceptable ranges.
- Unit Conversion: Dimensions are converted to consistent units (meters) for calculation.
- Cross-sectional Area: Calculate the cross-sectional area using the formula (A + B - t) × t.
- Volume Calculation: Multiply the cross-sectional area by the length.
- Weight Determination: Multiply the volume by the material density.
- Result Formatting: Present the result in appropriate units with proper precision.

Volume = (50 + 50 - 5) × 5 × 0.001 × 6 = 0.00285 m³
Weight = 0.00285 × 7850 = 22.37 kg
Formula Used
The structural angle weight calculation is based on fundamental physics and engineering principles:
Weight (kg) = Density (kg/m³) × Volume (m³)
Volume (m³) = Cross-sectional Area (m²) × Length (m)
Cross-sectional Area = (A + B - t) × t
Where:
• A = First leg dimension (m)
• B = Second leg dimension (m)
• t = Thickness (m)
• L = Length (m)
Why This Formula?
The formula (A + B - t) × t represents the cross-sectional area of an L-shaped angle. This accounts for:
- The area of both legs combined
- Subtraction of the overlap at the corner to avoid double-counting
- Multiplication by thickness to get the actual cross-sectional area
Material Densities:
- Steel: 7850 kg/m³
- Aluminum: 2700 kg/m³
- Stainless Steel: 7930 kg/m³
- Brass: 8500 kg/m³
- Copper: 8960 kg/m³

Practical Examples
Here are some real-world examples of structural angle weight calculations:
Example 1: Standard Steel Angle
Specifications:• First Leg: 75mm
• Second Leg: 75mm
• Thickness: 6mm
• Length: 12m
• Material: Steel (7850 kg/m³)
Calculation:
Volume = (75 + 75 - 6) × 6 × 0.001 × 12 = 0.01037 m³
Weight = 0.01037 × 7850 = 81.41 kg
Example 2: Aluminum Angle for Aircraft
Specifications:• First Leg: 40mm
• Second Leg: 60mm
• Thickness: 3mm
• Length: 2.5m
• Material: Aluminum (2700 kg/m³)
Calculation:
Volume = (40 + 60 - 3) × 3 × 0.001 × 2.5 = 0.000728 m³
Weight = 0.000728 × 2700 = 1.96 kg
Example 3: Stainless Steel Marine Application
Specifications:• First Leg: 100mm
• Second Leg: 100mm
• Thickness: 10mm
• Length: 6m
• Material: Stainless Steel (7930 kg/m³)
Calculation:
Volume = (100 + 100 - 10) × 10 × 0.001 × 6 = 0.0114 m³
Weight = 0.0114 × 7930 = 90.40 kg
Frequently Asked Questions (FAQ)
