Steel Plate Weight Calculator (kg, lb, tonne)

Quickly calculate the weight of steel plates by thickness, length, width, density, and quantity. Supports carbon steel, stainless steel, and coated steel plates with instant results.

Knowing the exact steel plate weight is essential for pricing, shipping cost estimation, and structural planning. This steel plate weight calculator helps engineers, fabricators calculate plate weight accurately using standard formulas and material densities.

How to Calculate Steel Plate Weight

The steel plate weight is calculated based on length, width, thickness, and material density. Whether you are calculating the weight of a carbon steel plate, stainless steel plate, or galvanized plate, the same basic formula applies.

Steel Plate Weight Formula:

Weight (kg) = Length (m) × Width (m) × Thickness (m) × Density (kg/m³).

Steel Plate Density Reference

• Carbon steel plate density: approx. 7850 kg/m³
• Stainless steel plate density: approx. 7700–8000 kg/m³
• Galvanized steel plate density: approx. 7650–7850 kg/m³

You can select a material from the calculator to autofill density, or enter a custom value if needed.

Frequently Asked Questions (FAQ)

• Q1. How do you calculate the weight of a steel plate?
  A: Multiply length × width × thickness × density. For carbon steel, the density is typically 7850 kg/m³.
• Q2. What is the weight of a 10mm steel plate?
  A: A 10mm thick steel plate weighs approximately 78.5 kg per square meter (kg/m²). The total weight depends on the plate’s length and width.
• Q3. What is the standard density of steel plates?
  A: Carbon steel plates are typically 7850 kg/m³, while stainless steel ranges from 7700 to 8000 kg/m³ depending on the grade.
• Q4. How do you calculate steel plate weight in kg?
  A: Use the formula:
  Weight (kg) = Length (m) × Width (m) × Thickness (m) × 7850
• Q5. Can I calculate steel plate weight in kg, lb, or tons?
  A: Yes. This calculator supports multiple units including kilograms (kg), metric tons (t), and pounds (lb).
