Sheet Weight Calculator
Estimate rectangular metal sheet mass using dimensions and a stated density table.
A QUICK WALKTHROUGH
How to use this tool
- Enter the values in the stated units.
- Choose decimal places and calculate.
Formula and units
m = L × W × t × ρ ÷ 1,000,000,000; L, W, t: mm; ρ: kg/m³; m: kg
Scope and limitations
Full rectangular, uniform sheet only. Holes, coatings, thickness tolerances and alloy variation are excluded. These typical densities estimate mass, not certified weight or lifting capacity.
Precision and input limits
Enter every value as a finite number greater than 0 and no greater than 1,000,000,000. Display 0–6 decimal places. JavaScript floating-point arithmetic is used; display rounding does not increase accuracy.
