Engineering tools built by someone who uses them.
Red Planet Software is a UK-based sole trader building professional calculation tools for the steel, metals, plastics and timber industries.
Every tool in the range comes from direct experience of the daily calculations that steel stockholders, fabricators, engineers and material suppliers deal with — weight per metre, cutting optimisation, material costing, metric-imperial conversion. These are the jobs that get done on scraps of paper, in spreadsheets, or with a calculator and a density table. Red Planet Software turns them into something faster and more reliable.
Cutting Calculator optimises how stock bars are cut to produce required lengths with minimum waste. It handles multiple stock lengths, kerf, trim and hold allowances, and produces visual cutting patterns and professional PDF reports with full material costing.
Metal Calculator Plus calculates weight per metre, weight per bar and total weight for round bar, polygon (hexagon, octagon), flat bar, plate and sheet, tube, hollow section and turning stock — across 50+ metals from mild steel and stainless to brass, titanium and phosphor bronze. Includes commercial rounding, turning cost calculation, carbon equivalence (CEV), and metric-imperial conversion.
Material Calculator — Plastic and Material Calculator — Timber bring the same weight calculation approach to engineering plastics (Nylon, Acetal, PTFE, Polycarbonate, PAI and more) and hardwoods and softwoods (Oak, Pine, Walnut, Iroko and more). Both show the round bar size needed to machine non-round shapes, so you know what stock to order.
The CutCalc + MetCalc Bundle puts both flagship tools together at roughly 15% less than buying them separately.
All products are licensed annually per seat. Each seat is tied to a single machine. Volume discounts apply at 5, 10, 25 and 50 seats. For larger deployments, get in touch for a quote.
