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

Across-flats unit Across flats Piece length unit Piece length Number of pieces Whole pieces only.Material density (kg/m³) Use documented density for the actual material/alloy.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

254.94 kg · 562.04 lb

4.2489 kg/m · 2.8552 lb/ft

541.266 mm² regular-hex cross-section · 25.494 kg per entered-length piece

254.94 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. Regular hex area = (√3 ÷ 2) × 25² = 541.266 mm².
2. Unit mass = 541.266 × 10⁻⁶ × 7,850 = 4.2489 kg/m.
3. Piece mass = 4.2489 × 6 = 25.494 kg.
4. Net batch = 25.494 × 10 = 254.936 kg.

This is theoretical mass for a solid regular hex bar using the entered across-flats size and density. Corner geometry, dimensional tolerance, coating and alloy chemistry can change delivered mass; use certified supplier data for contractual, lifting-critical or safety-critical work.
