Calculation Steps
- Calculate Cross-sectional Area: Area = (Leg1 × Thickness) + (Leg2 × Thickness) - (Thickness × Thickness)
- Convert Area to m²: Divide the area in mm² by 1,000,000
- Apply Material Density: Volume = Area × Length, Weight = Volume × Density
- Convert to Desired Unit: Convert final weight to selected unit (kg, lbs, or tons)
About This Calculator
The Unequal Angle Weight Calculator is designed specifically for structural engineers, construction professionals, and steel fabricators who need accurate weight calculations for unequal leg steel angles. This tool provides instant calculations based on standard steel densities and engineering formulas.
Unequal angles, also known as unequal leg angles or L-sections, are widely used in construction for bracing, support structures, and architectural applications. The calculator accounts for the different leg lengths and provides precise weight calculations essential for load calculations and material ordering.
How to Use
- Enter Dimensions: Input the length of both legs in millimeters. The first leg is typically the longer one.
- Specify Thickness: Enter the thickness of the angle section in millimeters.
- Set Length: Input the total length of the angle section in meters.
- Choose Units: Select your preferred weight unit (kg, lbs, or tons).
- Select Material: Choose the material type (steel, aluminum, or stainless steel).
- Calculate: Click the "Calculate Weight" button to get instant results.
Formula Used
Cross-sectional Area:
A = (L1 × t) + (L2 × t) - (t × t)
Weight Calculation:
Weight = A × Length × Density
Where: L1 = First leg length, L2 = Second leg length, t = Thickness
