Metal Weight Formula:
From: | To: |
Definition: This calculator estimates the weight of metal based on its length, cross-sectional area, and material density.
Purpose: It helps engineers, fabricators, and metalworkers determine material weights for construction, manufacturing, and logistics.
The calculator uses the formula:
Where:
Explanation: The length is multiplied by cross-sectional area to get volume, then multiplied by density to calculate weight.
Details: Accurate weight calculations are essential for structural design, material procurement, transportation planning, and cost estimation.
Tips: Enter the length in meters, cross-sectional area in m², and density (default 7850 kg/m³ for steel). All values must be > 0.
Q1: What's the default density value?
A: The default is 7850 kg/m³, which is typical for carbon steel. Adjust for other metals (2700 for aluminum, 8940 for copper).
Q2: How do I find cross-sectional area?
A: For standard shapes: square = side², rectangle = width × height, circle = π × radius².
Q3: Can I calculate weight in pounds?
A: Convert kg to lbs by multiplying by 2.20462 or change density to lbs/ft³ (490 for steel).
Q4: What if my metal has a complex shape?
A: Break it down into simpler shapes or use CAD software to calculate the cross-sectional area.
Q5: Does this include material tolerances?
A: No, consider adding 2-5% to account for material variations and manufacturing tolerances.
