Stainless steel is sold per kilogram, so knowing the weight of a sheet is the same as knowing its cost. Here's the formula Indian fabricators use, the density of each grade, and a ready chart for the standard 8×4 ft sheet.
The weight formula (works for any sheet)
Weight in kg = Length (mm) × Width (mm) × Thickness (mm) × Density (g/cc) ÷ 1,000,000. For example, a 2438 × 1219 mm (8×4 ft) 304 sheet at 1.5 mm: 2438 × 1219 × 1.5 × 7.93 ÷ 1,000,000 ≈ 35.4 kg.
Density by grade
| Grade | Density (g/cc) |
|---|---|
| 304 / 304L | 7.93 |
| 316 / 316L | 8.00 |
| 201 / 202 | 7.93 |
| 430 | 7.70 |
| 410 | 7.74 |
| Duplex 2205 | 7.80 |
Weight of a standard 8×4 ft 304 sheet
| Thickness (mm) | Approx weight (kg) |
|---|---|
| 0.8 | 18.9 |
| 1.0 | 23.6 |
| 1.2 | 28.3 |
| 1.5 | 35.4 |
| 2.0 | 47.2 |
| 2.5 | 58.9 |
| 3.0 | 70.7 |
| 4.0 | 94.3 |
| 5.0 | 117.9 |
| 6.0 | 141.5 |
Standard sheet & coil sizes in India
- 8 × 4 ft = 2438 × 1219 mm — the most common sheet size.
- 8 × 3 ft = 2438 × 914 mm.
- 10 × 4 ft = 3048 × 1219 mm; 12 × 4 ft = 3658 × 1219 mm.
- Coil widths commonly 1219, 1250 and 1500 mm, slit to order.
Turning weight into cost
Your sheet cost = weight × ₹/kg rate, plus 18% GST. Taking 304 at an indicative ₹210/kg, an 8×4 ft × 1.5 mm sheet (≈ 35.4 kg) works out to roughly ₹7,400 before GST. Check live indicative rates on our Shop page and use the weight calculator on the Technical page for your exact size.
Quick answers
How do you calculate stainless steel sheet weight?
Weight (kg) = Length (mm) × Width (mm) × Thickness (mm) × density (g/cc) ÷ 1,000,000. Use 7.93 for 304, 8.00 for 316, 7.93 for 202 and 7.70 for 430.
How much does an 8×4 ft 304 sheet weigh?
It depends on thickness: about 23.6 kg at 1.0 mm, 35.4 kg at 1.5 mm and 47.2 kg at 2.0 mm for a 2438×1219 mm 304 sheet. 316 is roughly 1% heavier.
Is 316 stainless steel heavier than 304?
Slightly — 316/316L density is about 8.00 g/cc versus 7.93 for 304, so a same-size 316 sheet weighs roughly 1% more.
