How It Works
The weight of a rectangular plate is calculated by multiplying its volume by the material density.
The Formula
Imperial: Weight (lbs) = Length (in) × Width (in) × Thickness (in) × Density (lbs/in³)
Metric: Convert mm to inches (mm × 0.0393701), calculate in lbs, then convert to kg (lbs × 0.453592)
Example
A 48" × 24" × 0.5" steel plate:
48 × 24 × 0.5 × 0.284 = 163.58 lbs
Material Densities
| Material | lbs/in³ | kg/m³ |
|---|---|---|
| Steel (A36) | 0.284 | 7,861 |
| Stainless Steel | 0.289 | 8,000 |
| Aluminum (6061) | 0.098 | 2,713 |
| Copper | 0.321 | 8,890 |
| Titanium (Grade 2) | 0.163 | 4,510 |
| Acrylic | 0.043 | 1,190 |
| Glass | 0.091 | 2,520 |
| Pine Plywood | 0.025 | 692 |
When to Use a Metal Weight Calculator
Estimating Material Costs
Steel is sold by the pound. Knowing the weight of your plate lets you estimate material cost before ordering.
Project Planning
Calculate the weight of raw materials for your welding project to ensure your workbench and fixtures can handle the load.
Structural Engineering
Engineers need dead load calculations for supports, foundations, and rigging. This tool gives you quick estimates for 8 common materials.
