If your sheet is specified by gauge number, use the built-in Gauge → mm Converter strip. Select SWG, BWG or MSG standard, pick the gauge number and click Use This Thickness — thickness fills in automatically.
Select mm, Inches or Feet using the unit toggle. All dimension labels and unit indicators update instantly — no manual conversion needed.
Select Rectangular Sheet for standard flat sheets (length × width) or Circular / Round Sheet for disc-shaped blanks used in spinning, pressing and stamping operations.
Enter length, width (or diameter), thickness and number of sheets. Standard Indian market sheet sizes are 2500×1250 mm, 2000×1000 mm and 3000×1500 mm. Results update automatically as you type.
Results show weight per sheet, total kg, metric tonnes (MT), kg/m² (compare with supplier data), sheet area and total area for paint estimation — all six values update instantly on every input change.
Exact step-by-step method for rectangular and circular sheet weight calculation
For any material: kg/m² = Thickness (mm) × Density (g/cm³). For MS sheets (7.85): 1 mm thick = 7.85 kg/m². So 2 mm MS sheet = 15.70 kg/m², 3 mm = 23.55 kg/m². This rule is used by every Indian steel stockist for quick quotes.
Length × Width × Thickness in mm gives volume in mm³. One cm³ = 1000 mm³. Density is in g/cm³. So mm³ ÷ 1000 = cm³, then × g/cm³ = grams, then ÷ 1000 = kg. Combined: mm³ × density ÷ 1,000,000 = kg directly.
GI (Galvanised Iron) sheets have a zinc coating of 120–275 g/m² (IS 277 coating classes Z120 to Z275). The calculator uses base metal density 7.85 — add approximately 0.12–0.28 kg/m² separately for the zinc coating weight in precision applications.
Weight/sheet = 2500 × 1250 × 1.6 × 7.85 ÷ 1,000,000
= 5,000,000,000 × 1.6 × 7.85 ÷ 1,000,000
= 5,000,000 × 7.85 ÷ 1,000,000 × 1.6
= 39.25 kg/sheet
Total = 39.25 × 50 = 1,962.5 kg = 1.963 MT

Standard density values for all common sheet metals used in Indian fabrication, construction and manufacturing
Always confirm density with mill test certificate for critical applications. GI sheet weight includes base metal only — zinc coating weight must be added separately per IS 277:2008 coating class.
Key sectors where MS, GI, SS and aluminium sheets are used across India
Cold rolled IS 513 sheets are the primary body panel material for passenger vehicles, two-wheelers and commercial vehicles. Maruti, Tata Motors, Mahindra and Hyundai consume millions of tonnes of IS 513 CR2/CR4 sheets annually from JSW, SAIL and AMNS India.
GI corrugated sheets (IS 277) are the most common low-cost roofing material across rural and industrial India. Pre-painted GI (PPGI) sheets from Tata BlueScope and JSW cover industrial sheds, warehouses and rural housing nationwide.
SS 304 and SS 202 sheets are fabricated into commercial kitchen equipment, food processing vessels, dairy tanks and pharmaceutical storage. India's FSSAI regulations mandate stainless steel contact surfaces for food production equipment.
GI sheets (22G to 18G, IS 277) are the standard material for air conditioning ductwork across Indian commercial buildings, hospitals, IT parks and metro stations. Sheet weight calculation determines material cost and duct hanger capacity.
Aluminium sheets form the back sheet and junction box covers of solar panels. CR steel sheets are pressed into electrical panel enclosures, distribution boards and switchgear cabinets widely used across India's growing power infrastructure.
HR plates and sheets from IS 2062 are used in Indian Navy and Coast Guard vessel construction at Mazagon Dock and Cochin Shipyard. SS 316 sheets are used in marine-grade applications requiring high corrosion resistance in saline environments.
Best practices used by Indian sheet metal fabricators, procurement teams and QS engineers
Sheet metal cutting (shearing, laser, plasma, waterjet) always produces off-cuts. For simple rectangular blanks from standard sheets, add 5%. For complex nested profiles, add 8–15% depending on blank shape efficiency. Use the nesting layout to minimise waste before ordering. Indian fabricators typically add 7% to calculated net weight for procurement.
IS 513:2008 allows a thickness tolerance of −0.04 to +0.10 mm for sheets under 1.6 mm. For 1.6–2.5 mm, tolerance is −5% to +8%. Actual sheet weight may be up to 5% lower than nominal due to under-thickness rolling. For precision weight requirements, always order with tight tolerance specification or verify with calliper measurement at goods receipt.
Cold Rolled (IS 513) and Hot Rolled (IS 1079) sheets have the same density (7.85 g/cm³) — they weigh the same per mm thickness. The difference is surface finish, mechanical properties and dimensional tolerance. CR sheets are thinner, more dimensionally accurate and have better surface finish than HR sheets of the same nominal thickness.
The Total Area result from this calculator gives the surface area in m² for both sides combined (multiply by 2 for two-sided painting). At 12–14 m² per litre for standard zinc phosphate primer, divide total area by coverage rate to get paint quantity. For powder coating, area determines cost at approximately ₹40–80 per m² at Indian job shops in 2026.
As of 2026 approximate ex-Mumbai prices: IS 513 CR sheet ₹62,000–₹72,000/MT; IS 277 GI sheet ₹75,000–₹88,000/MT; SS 304 2B sheet ₹2,00,000–₹2,30,000/MT; SS 202 ₹1,20,000–₹1,45,000/MT; Aluminium 5052 ₹2,10,000–₹2,40,000/MT. Prices change weekly — always get fresh quotes from your local stockist or JSW/SAIL dealer.
For automotive, pharma, food and defence applications, always request the Mill Test Certificate (MTC) showing chemical composition, mechanical properties, coating weight (for GI) and actual thickness measurement. IS 513, IS 277 and IS 6911 all mandate MTC documentation for BIS-certified material — mandatory for government, IATF and FSSC 22000 compliant supply chains.
