Plate Weight Calculator
Find weight per plate and total weight from material and dimensions.
Results
Total weight
- Weight per plate
- 39.25 kg86.53 lb
- Volume per plate
- 0.005 m³
Actual mass varies with alloy, dimensional tolerances and surface treatments. Holes, cutouts, chamfers and coatings are not included. Weight here means mass, expressed in kg or lb, rather than gravitational force.
Formula · How it works
Formula
V = L × W × t; m = V × ρ; mₜ = m × qVolume per plate V = length × width × thickness. Mass per plate m = Vρ. Total mass = m × quantity. SI calculation uses dimensions in m and density in kg/m³.
Worked example
A 1,000 × 500 × 10 mm plate has a volume of 0.005 m³. At a nominal carbon steel density of 7,850 kg/m³, one plate weighs 39.25 kg; two plates weigh 78.50 kg.
How it works
The calculator treats each plate as a solid rectangular block with uniform density. Material presets provide nominal values for an estimate. Use the density for your actual alloy when it is available.
Common questions
Are the material densities exact?
No. Presets are nominal estimates. Density varies by alloy and condition; use a supplier or material specification value with custom density when available.
Does the calculator subtract holes or cutouts?
No. It calculates a solid rectangular plate. Subtract the removed volume and its corresponding mass separately for a plate with cutouts.
