Calculation Examples
Example 1: Steel Plate
Dimensions: 2000mm × 1000mm × 10mm
Material: Mild Steel (7.85 g/cm³)
Calculation: 200cm × 100cm × 1cm × 7.85 g/cm³ = 157,000g = 157kg
Result: 157 kg (346 lbs)
Example 2: Aluminum Plate
Dimensions: 48" × 24" × 0.25"
Material: Aluminum (2.7 g/cm³)
Calculation: 121.92cm × 60.96cm × 0.635cm × 2.7 g/cm³ = 12,714g = 12.7kg
Result: 12.7 kg (28 lbs)
Example 3: Stainless Steel Plate
Dimensions: 1.5m × 0.8m × 5mm
Material: Stainless Steel 304 (7.7 g/cm³)
Calculation: 150cm × 80cm × 0.5cm × 7.7 g/cm³ = 46,200g = 46.2kg
Result: 46.2 kg (102 lbs)
Frequently Asked Questions
How do you calculate the weight of a steel plate?
To calculate steel plate weight, multiply length × width × thickness × density. For mild steel, use a density of 7.85 g/cm³ or 0.284 lb/in³.
What is the density of common metals?
Common metal densities: Steel (7.85 g/cm³), Aluminum (2.7 g/cm³), Copper (8.9 g/cm³), Brass (7.14 g/cm³), Stainless Steel (7.7-8.0 g/cm³).
Can I use different units for different dimensions?
No, all dimensions must be in the same unit system. Convert all measurements to the same unit before calculating.
How accurate are the calculations?
The calculator provides theoretical weights based on material densities. Actual weights may vary slightly due to manufacturing tolerances and material composition variations.
What if my material is not listed?
Select "Custom Density" from the material dropdown and enter the specific density of your material in kg/m³.
