How do I calculate MS plate weight in kg?

Use Weight (kg) = length(mm) x width(mm) x thickness(mm) x 7.85 / 1,000,000. The 7.85 factor comes from mild steel density of 7,850 kg/m3. For example, a 2000 x 1000 x 10 mm MS plate weighs 157 kg.

What is the MS plate weight calculation formula?

For a rectangular plate, Weight = L x W x T x density / 1,000,000,000 when L, W, and T are in mm and density is kg/m3. For mild steel, this simplifies to L x W x T x 7.85 / 1,000,000.

What is the weight of a 10 mm MS plate per square meter?

A 10 mm mild steel plate weighs 78.5 kg per square metre because kg/m2 = thickness(mm) x 7.85. A 1 x 2 m plate at 10 mm thickness weighs 157 kg.

How much does a 2500 x 1250 x 10 mm MS plate weigh?

A 2500 x 1250 x 10 mm mild steel plate weighs 245.31 kg. The calculation is 2500 x 1250 x 10 x 7.85 / 1,000,000.

How do I calculate MS chequered plate weight?

First calculate the flat plate weight from length, width, thickness, and density. Then add a pattern allowance for the raised chequered surface. Ganak uses a 5% default allowance, but you can edit it to match your supplier's chequered plate chart.

What density should I use for mild steel plate?

Use 7,850 kg/m3 for mild steel plate in most engineering and procurement estimates. Some supplier charts use the shortcut 7.85 g/cm3, which is the same density expressed in different units.

How do I calculate circular MS plate weight?

Use Weight = (pi / 4) x diameter(mm)^2 x thickness(mm) x density / 1,000,000,000. For mild steel, use density 7,850 kg/m3. Select circular shape in the calculator to use this automatically.

Does the calculator handle bolt holes in base plates?

Yes. Enable bolt-hole deduction, enter the number of holes and hole diameter, and the calculator subtracts the removed circular area before calculating weight.

Why is supplier plate weight different from calculated weight?

The calculator gives theoretical weight from nominal dimensions and density. Supplier invoices may differ because of rolling tolerances, chequered pattern geometry, edge trimming, surface coating, and rounding rules.

Can I use this as an MS plate weight calculation formula PDF replacement?

Yes for quick estimates and formula checks. The page includes the formula, kg/m2 chart, examples, and shareable URL state. For contractual procurement, still verify against the supplier's material test certificate or weight chart.

What Is an MS Plate Weight Calculator?

Calculate mild steel plate weight in kg for fabrication, procurement, transport, and costing.

An MS plate weight calculator estimates the weight of a mild steel plate from its length, width, thickness, and material density. It is commonly used by fabricators, steel traders, engineers, and site teams before ordering plates, cutting base plates, estimating freight, or preparing quotations.

Ganak keeps the calculator-first flow: enter the plate dimensions at the top, then use the supporting formula, chart, and examples below only when you need to verify the calculation.

MS Plate Weight Calculation Formula

The standard formula and the practical mild steel shortcut.

Rectangular MS plate

Weight (kg) = Length(mm) x Width(mm) x Thickness(mm) x 7.85 / 1,000,000

Example: 2000 x 1000 x 10 mm = 157 kg.

Circular MS plate

Weight (kg) = (pi / 4) x Diameter(mm)^2 x Thickness(mm) x 7.85 / 1,000,000

Use this for round plates, circular base plates, and disc-shaped blanks.

Weight per square metre

kg/m2 = Thickness(mm) x 7.85

A 10 mm MS plate weighs 78.5 kg per square metre before allowances.

25 mm	196.25 kg/m2	392.50 kg

Chequered Plate Weight Calculation

Chequered pattern weight varies by supplier, so the allowance stays editable.

MS chequered plates have raised patterns, so their actual weight is higher than a plain plate of the same nominal thickness. Ganak uses a practical default and keeps the allowance editable because pattern geometry varies by supplier.

Default allowance

Useful for quick estimates before supplier confirmation.

Editable range

0-20%

Match your supplier's chequered plate chart when exact pattern weight matters.

Circular/Base Plate and Hole Deduction Examples

Use the advanced options when area is not a full rectangle.

Hole deduction

Base plates with bolt holes

Subtract circular anchor holes before multiplying by thickness and density.

Circular area

Round MS plates

Use pi/4 x D^2 for discs, flanges, and circular blanks.

Common Mistakes

Avoid these errors when comparing supplier quotes or weight charts.

Mixed units

The MS shortcut assumes all dimensions are in mm.

Wrong plate type

Chequered patterns add material beyond plain plate weight.

Ignored holes

Small base plates can lose meaningful weight through bolt holes.

Supplier tolerance

Invoices can differ because of rolling tolerance and rounding.
