⚙️ Plate Weight Calculator
Calculate metal plate weight based on dimensions and metal type
How to Use This Calculator
Enter Plate Dimensions
Input the length, width, and thickness of your metal plate in inches. Measure all three dimensions accurately for precise weight calculations.
Select Metal Type
Select the type of metal (steel, aluminum, copper, brass, etc.). Different metals have different densities, which significantly affects weight.
Calculate and Review
Click "Calculate Plate Weight" to see plate weight, area, and weight per square foot. Use this information for transportation, handling, and cost estimation.
Plan Transportation
Use the calculated weight to plan transportation, verify equipment capacity, and estimate shipping costs. Heavier plates like steel require stronger equipment.
Formula
Volume (cu ft) = Length (ft) × Width (ft) × Thickness (ft)
Convert Inches to Feet: Divide by 12
Plate Area (sq ft) = (Length × Width) ÷ 144
Weight (lbs) = Volume (cu ft) × Density (lbs/cu ft)
Weight per Sq Ft = Thickness (ft) × Density (lbs/cu ft)
Example 1: Steel Plate (24" × 12" × 0.5")
Step 1: Convert to feet: 24" = 2 ft, 12" = 1 ft, 0.5" = 0.0417 ft
Step 2: Calculate volume: 2 × 1 × 0.0417 = 0.0834 cu ft
Step 3: Calculate area: (24 × 12) ÷ 144 = 2 sq ft
Step 4: Steel density: 490 lbs/cu ft
Step 5: Calculate weight: 0.0834 × 490 = 40.87 lbs
Step 6: Weight per sq ft: 0.0417 × 490 = 20.43 lbs/sq ft
Example 2: Aluminum Plate (48" × 24" × 0.25")
Step 1: Convert to feet: 48" = 4 ft, 24" = 2 ft, 0.25" = 0.0208 ft
Step 2: Calculate volume: 4 × 2 × 0.0208 = 0.166 cu ft
Step 3: Calculate area: (48 × 24) ÷ 144 = 8 sq ft
Step 4: Aluminum density: 169 lbs/cu ft
Step 5: Calculate weight: 0.166 × 169 = 28.05 lbs
Step 6: Weight per sq ft: 0.0208 × 169 = 3.52 lbs/sq ft

Frequently Asked Questions
How much does a metal plate weigh?
Metal plate weight depends on dimensions and metal type. For example, a 24" × 12" × 0.5" steel plate weighs approximately 40.87 lbs, while the same size aluminum plate weighs only 14.07 lbs. Use the calculator with your specific dimensions and metal type.
How do I calculate weight per square foot?
Weight per square foot = Thickness (feet) × Density (lbs/cu ft). For 0.5 inch (0.0417 ft) steel: 0.0417 × 490 = 20.43 lbs/sq ft. The calculator shows weight per square foot in the results.
Which metal is heaviest?
Copper and bronze are among the heaviest common metals (556 and 547 lbs/cu ft respectively). Steel weighs 490 lbs/cu ft, aluminum weighs only 169 lbs/cu ft. Heavier metals require stronger equipment for handling and transportation.
Does metal type affect plate weight?
Yes! Metal type significantly affects plate weight due to different densities. Steel plates weigh almost 3× more than aluminum plates of the same dimensions. Always specify the correct metal type for accurate weight calculations.
Can I calculate weight for irregular shapes?
This calculator works for rectangular plates. For irregular shapes, calculate the volume manually (approximate as rectangular dimensions) and use the metal density with the calculated volume.
How accurate is this calculator?
This calculator provides accurate estimates based on standard metal densities. Actual weight may vary slightly based on specific alloy composition, grade, and manufacturing process. Use the calculator as a guide and add safety margins for equipment capacity.
