1. Introduction 

The Angle Weight Calculator is a free online tool designed for engineers, fabricators, metalworkers, and students to quickly calculate the weight of steel angles and other materials such as aluminum, copper, or brass. Whether you’re working with equal or unequal angle sections, this tool simplifies weight estimation based on user-provided dimensions and material type.

This calculator is especially helpful for those who need accurate weight values for planning fabrication, transportation, cost estimation, or inventory management.

2. What Is an Angle Section?

An angle section is a type of structural steel profile shaped like an “L”. It consists of two legs (commonly labeled Side A and Side B) connected at a right angle. Angle sections are widely used in construction, frameworks, brackets, supports, and reinforcements due to their strength and lightweight properties.

There are two types:

• Equal angle – both legs are the same length.

• Unequal angle – legs are of different lengths.

3. How to Use the Angle Weight Calculator

3.1 Input Fields

To calculate the weight, fill in the following fields:

• Material: Choose from materials like mild steel, stainless steel, aluminum, copper, etc.

• Side A: The first leg of the angle.

• Side B: The second leg of the angle.

• Thickness (T): Thickness of the angle.

• Length: Total length of the angle piece.

Each field lets you select from various units such as millimeters (mm), centimeters (cm), meters (m), inches (in), and feet (ft).

3.2 Results

Once you click “Calculate”, the tool displays:

• Weight in kilograms (kg)

• Weight in pounds (lbs)

You can also reset the values with the “Reset” button for a new calculation.

4. Formula Used for Angle Weight Calculation

The calculator uses the following formula:

Where:

• A = Side A (in meters)

• B = Side B (in meters)

• T = Thickness (in meters)

• L = Length (in meters)

• Density = Material density (in kg/m³)

This formula calculates the cross-sectional area and multiplies it by the length and density to provide the final weight.

5. Unit Conversion Feature

The tool automatically converts all input units to meters before applying the formula. Supported units:

• mm → 0.001 m

• cm → 0.01 m

• in → 0.0254 m

• ft → 0.3048 m

This feature makes the calculator flexible for global use regardless of the measurement system.

6. Supported Materials and Densities

You can choose from over 10 materials, each with standard densities:

• Mild Steel – 7850 kg/m³

• Stainless Steel – 8030 kg/m³
