Weight per square meter by material (10 mm thickness)
The figures below show weight per square meter at a fixed 10 mm thickness for each supported material, illustrating how much density alone drives the difference in plate weight between materials.
| Material | Density (kg/m³) | 1 m² × 10 mm plate weight |
|---|---|---|
| Steel | 7,850 | 78.5 kg/m² |
| Stainless steel | 8,000 | 80.0 kg/m² |
| Aluminium | 2,700 | 27.0 kg/m² |
| Copper | 8,940 | 89.4 kg/m² |
| Brass | 8,500 | 85.0 kg/m² |
- The weight-per-m² figures above assume 10 mm thickness for comparison; weight per m² scales linearly with thickness for a given material.
- This is an estimating calculator; for lifting-plan, crane-capacity, or code-stamped fabrication documentation, confirm plate weight against the mill certificate.
What is a plate weight calculator?
Plate weight is a straightforward volume-times-density calculation: length × width × thickness gives volume, and multiplying by material density gives mass. This calculator supports steel, stainless steel, aluminium, copper, and brass, using standard published density values for each, and multiplies by quantity to give a total weight for multiple identical plates.
Plate weight matters for fabrication planning, shipping cost estimates, and lifting or crane-capacity planning, where knowing the weight of a plate or a batch of plates in advance is important for safe handling.
This is an estimating tool. For lifting-plan, crane-capacity, or code-stamped fabrication documentation, plate weight should be confirmed against the mill certificate rather than this generic estimate.
How to use this plate weight calculator
- Select the material: steel, stainless steel, aluminium, copper, or brass.
- Enter the plate length.
- Enter the plate width.
- Enter the plate thickness.
- Enter the quantity of identical plates.
- Read the total weight, weight per piece, and weight per square meter.
The formula behind plate weight
Weight per piece is the plate's volume (length × width × thickness) multiplied by material density. Total weight scales that figure by the quantity entered, and weight per square meter isolates the thickness-and-density portion of the calculation for comparing different plate thicknesses.
Common mistakes
- Forgetting to update the quantity field when ordering multiple identical plates, which understates total shipping or lifting weight.
- Mixing millimeter and meter values across fields, since this calculator's length and width fields expect millimeters and convert internally.
- Using the generic density for a specialty alloy where the mill certificate lists a different value.
- Underestimating rigging and crane capacity by relying on an estimate rather than a confirmed mill weight for heavy or safety-critical lifts.
자주 묻는 질문
How is plate weight calculated?
Plate weight equals volume (length × width × thickness) multiplied by material density. This calculator also multiplies by quantity to give a total weight for a batch of identical plates.
What materials does this calculator support?
Steel, stainless steel, aluminium, copper, and brass, each using a standard published density value.
Why does weight per m² matter?
Weight per square meter isolates the effect of thickness and material density, making it easy to compare how much a given plate thickness weighs across different materials without recalculating for a specific plate size.
How accurate is this for crane or lifting planning?
It is a reasonable planning estimate based on nominal dimensions and standard density, but for lifting-plan and crane-capacity documentation, weight should be confirmed against the mill certificate, since actual dimensional tolerances and alloy composition can shift the true weight.
Does quantity multiply the total weight correctly for mixed orders?
The quantity field assumes all pieces share the same material, length, width, and thickness; for an order with mixed plate sizes, calculate each size separately and add the results together.
