Steel Plate Weight Calculator
Estimate the weight of steel plates for fabrication and construction
Enter the length, width, and thickness of your steel plate (in millimeters), the number of plates, and the steel's density (default is 7850 kg/m³). The calculator will estimate the weight of a single plate and the total weight for your order.
The calculator uses the following formula:
- Volume (m³) = Length × Width × Thickness (all in meters)
- Weight (kg) = Volume × Density
The total weight is the weight per plate multiplied by the number of plates.
- Plate dimensions: Larger plates weigh more.
- Steel density: Different steel grades may have slightly different densities.
- Quantity: More plates increase total weight.
- Cutouts/holes: Subtract volume for large holes if needed.
- Structural steel fabrication
- Machine bases and supports
- Construction and engineering projects
- Metalworking and manufacturing
- Use proper lifting equipment for heavy plates.
- Wear gloves and safety gear to prevent injuries.
- Store plates on flat, stable surfaces.
- Check weights for transport and logistics planning.
How do I calculate the weight of a steel plate?
Multiply the plate's length, width, and thickness (in meters) to get the volume, then multiply by the steel's density (typically 7850 kg/m³). The calculator does this for you.
What is the standard density of steel?
Most steels have a density of about 7850 kg/m³. Check with your supplier for exact values if needed.
Should I include extra weight for coatings or holes?
If your plates have significant holes or coatings, adjust the calculated weight accordingly.
