Rectangular Tube Weight Formula:
| From: | To: |
The rectangular tube weight formula calculates the weight per meter of rectangular steel tubes based on their dimensions. This calculation is essential for material estimation, structural design, and cost calculation in construction and manufacturing.
The calculator uses the formula:
Where:
Explanation: The formula calculates the cross-sectional area and multiplies it by the material density to determine weight per unit length.
Details: Accurate weight calculation is crucial for structural engineering, material procurement, transportation planning, and cost estimation in construction projects.
Tips: Enter all dimensions in millimeters. Ensure accurate measurements for precise weight calculation. All values must be positive numbers.
Q1: Why use 0.00000785 as the density coefficient?
A: This value represents the density of steel (7850 kg/m³) converted to kg/mm³ for calculations with millimeter measurements.
Q2: Does this formula work for materials other than steel?
A: No, this specific formula is for steel rectangular tubes. For other materials, you would need to use the appropriate density value.
Q3: How accurate is this calculation?
A: The calculation provides a theoretical weight based on perfect geometry. Actual weight may vary slightly due to manufacturing tolerances.
Q4: Can I calculate total weight for a specific length?
A: Yes, multiply the weight per meter result by the total length in meters to get the total weight.
Q5: Are there different formulas for different tube shapes?
A: Yes, different formulas exist for round tubes, square tubes, and other profiles, each with their specific geometric calculations.
