No hidden assumptions. Inputs, units and the working stay visible so you can check the calculation.

Side unit Square side Piece length unit Piece length Number of pieces Whole pieces only.Material density (kg/m³) Carbon steel commonly uses 7,850 kg/m³; use documented alloy data when needed.Procurement allowance (%) Applied to order mass, not theoretical kg/m.Rate per kg (optional) 0 disables cost.Target mass unit Target mass (optional) Reverse-solves whole entered-length pieces.Supplier / measured kg per metre (optional) Reports variance without replacing theoretical geometry.

Calculated result

294.38 kg · 648.99 lb

4.9063 kg/m · 3.2968 lb/ft

625 mm² cross-section · 29.438 kg per entered-length piece

294.38 kg net batch mass

Enter rate/kg for procurement cost

Enter target mass for reverse whole-piece count

Enter supplier kg/m to compare table or delivered mass

1. Area = 25 × 25 = 625 mm².
2. Unit mass = 625 × 10⁻⁶ × 7,850 = 4.9063 kg/m.
3. Piece mass = 4.9063 × 6 = 29.438 kg.
4. Net batch = 29.438 × 10 = 294.375 kg.

This is theoretical mass for solid square stock from nominal side and entered density. Rolled corner radii, dimensional tolerance, coating and alloy chemistry can change delivered mass; use certified supplier data for contractual, lifting-critical or safety-critical work.
