Torque Unit Converter

This tool provides precise, cross-unit torque conversion for engineers, technicians, and students. It accepts a numeric torque value, a source unit, and a target unit, returning an equivalent value in the chosen unit. Primary use cases include verifying fastener torque specs, validating calibration data, and converting supplier data sheets to project units. It covers common SI and US customary torque units, enabling quick comparisons during design, assembly, and maintenance tasks. By grounding all conversions in a single base, the tool ensures consistency across standards and avoids manual calculation errors.
Conceptually, all torque units are mapped to a base scientific unit (newton meter). Each unit has a fixed conversion factor to N·m. The tool computes: value_in_Nm = value * factor(from_unit); then converted_value = value_in_Nm / factor(to_unit). Factors are defined for N·m, kN·m, N·cm, lbf·in, lbf·ft, and kgf·m, kgf·cm. It supports negative values to reflect direction, and can round results to a user-specified precision. Edge cases such as unsupported units or non-numeric input yield errors for robust downstream processing.
