# MachineCalcs

> Free mechanical and machine-design calculators that show the formula, the assumptions, and the source policy behind table-backed results — not just a number. Every tool works in both metric (SI) and imperial units and computes entirely in the browser.

MachineCalcs is an independent reference for engineers, machinists and designers. Each calculator states its governing equation and, when table-backed or code-adjacent, its source/standards boundary (ISO, AWS, DIN, ANSI/ASME, NFPA, supplier data or user-entered values). Tools are paired with explanatory guides and printable reference charts. The tools are a reference — not a substitute for a professional engineer’s review on safety-critical designs.
