Steel Plate Weight Calculator (mm)

Weight of a steel plate from mm dimensions — instant kg result using 7,850 kg/m³ carbon steel density.

—

Formula

Weight (kg) = L(mm) × W(mm) × T(mm) × 7,850 ÷ 10⁹ — the 7,850 kg/m³ mild-steel density folded into a mm-based shortcut

Frequently Asked Questions

How much does a 4x8 steel plate weigh?

A 1220 × 2440 mm (4×8 ft) plate at 6 mm weighs 1220×2440×6×850/10⁹ ≈ 140.2 kg; at 10 mm about 233.7 kg.

Is the formula different for stainless plate?

Only the density: use 7,900–8,000 kg/m³ instead of 7,850 — about 0.6–1.9% heavier. Multiply the result by 1.006–1.019.

What is steel plate weight per square metre?

Per m²: multiply thickness in mm by 7.85. A 10 mm plate is 78.5 kg/m²; 3 mm sheet is 23.6 kg/m².
