MS sheet cutting calculator
Mild steel is sold by the kilo and cut by the sheet. Work out how many sheets your parts need, what each sheet weighs, and what the job costs in rupees.
Price per sheet from price per kg
The sheet size comes from the calculator below. ₹65 a kg is only an example: use your dealer’s rate for the grade and thickness you buy.
How many sheets for the job?
An example job of plates, brackets and gussets is loaded, with a 3mm gap for gas or plasma cutting. Put in your own parts.
MS sheet weight
Weight = length (m) × width (m) × thickness (mm) × 7.85. A 2500×1250 sheet of 2mm: 2.5 × 1.25 × 2 × 7.85 = 49.1 kg.

Getting more parts from a sheet
Leave the right gap
Shearing leaves no gap, but gas cutting, plasma and laser each burn a different width. The kerf guide has typical figures.
Compare sheet sizes
Tap the sizes in the calculator: 2500×1250 and 8×4 can need a different number of sheets for the same parts.
Keep the offcuts
The calculator shows which strips are left over. Note them for gussets and small brackets on the next job.
Quote from the layout
The CutNest app prices the job for your customer from the sheets, the cutting time and your margin, in rupees.
