Formula Used

Weight = Length × Width × Thickness × Density

Where:

  • Length: Length of the plate
  • Width: Width of the plate
  • Thickness: Thickness of the plate
  • Density: Material density (varies by material)

Common Material Densities:

  • Mild Steel: 7.85 g/cm³ (7850 kg/m³)
  • Stainless Steel 304: 7.7 g/cm³ (7700 kg/m³)
  • Aluminum: 2.7 g/cm³ (2700 kg/m³)
  • Copper: 8.9 g/cm³ (8900 kg/m³)

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.
