Formula
peso = área × (esp/1000) × ρ
About this calculator
This calculator estimates the weight of metal sheets based on area, thickness, and material density. It uses the formula weight = area × (thickness in mm / 1000) × density, converting thickness from millimeters to meters. The result is given in kilograms.
You can use this tool to plan the transport of steel, aluminum, copper, or other metal sheets. For example, when purchasing sheets for a construction project, knowing the total weight helps calculate shipping costs and verify structural load capacity. Simply enter the width, length, thickness, and select the material.
Important precautions: density varies by metal alloy. For carbon steel, use 7850 kg/m³; for aluminum, 2700 kg/m³; for copper, 8960 kg/m³. Always confirm the exact density with your supplier. Also, the formula assumes uniform thickness; for irregular profiles, the calculation may not be accurate.
Frequently asked questions
How do I calculate the weight of a steel sheet?
Enter the width, length, and thickness (in mm), and select 'Steel' (density 7850 kg/m³). The calculator will return the weight in kg.
What is the density of aluminum used in the calculator?
The default density for aluminum is 2700 kg/m³. Check if your specific alloy has a different density and adjust manually.
Can I use this calculator for plastic sheets?
Yes, as long as you know the density of the plastic. Select 'Custom' and enter the density value in kg/m³.
Is the calculated weight the actual weight of the sheet?
It is an estimate. Variations in alloy composition and thickness tolerances may cause differences of up to 5%. For accuracy, weigh the sheet physically.
How do I convert weight from kg to pounds?
Multiply the result in kg by 2.20462 to get weight in pounds.
