Lb-ft to Nm Converter

About This Tool

This tool provides a precise torque conversion from pound-feet (lb-ft) to newton-meters (Nm). It is intended for engineers, technicians, and students who produce mechanical designs, test plans, or calibration data and require SI-aligned torque values in reports and simulations. The input represents torque, not energy, and the output is a numeric Nm value suitable for inclusion in specifications and calculations.
Conceptually, the calculation applies the standard factor 1 lb-ft = 1.355817948 Nm. The user supplies the lb-ft value; the tool computes the product and formats the result to four decimal places. This deterministic approach avoids rounding surprises in downstream analyses and ensures consistency across projects.
Unique value lies in its simplicity, speed, and explicit handling of domain constraints. It supports a single conversion direction (lb-ft to Nm) to minimize ambiguity and error, while maintaining readiness for future extension to other torque units. It is well suited for motor and gear calculations, mechanical design reviews, and quality control documentation.
Core features include numeric input validation (non-negative), fixed target unit Nm, and precise numeric output. Typical use cases include verifying motor torque ratings, converting lab data, and preparing SI-compliant figures for dashboards, spreadsheets, and CAD exports.
