kg m to Nm

A unit converter focused on composite SI units and torque-related calculations. It accepts numeric values with from_unit and to_unit like kg*m and N*m, and computes the equivalent quantity. For typical engineering scenarios, it supports both straightforward base-unit conversions and context-based mappings when additional information is provided. The tool is intended for engineers, technicians, students, and designers performing quick unit checks.
Conceptually, the tool first parses the input units and resolves their base dimensions using a standard unit registry. If the from and to units are dimensionally compatible, it applies a documented conversion factor. If not, it looks for a defined special-case pathway that uses user-supplied context (for example gravity) to enable an appropriate mapping.
Unique value lies in handling composite units and enabling torque-like conversions without external scripts. By offering optional g and lever-arm values, it supports scenarios where torque or rotational work depends on weight, distance, and acceleration. This keeps calculations transparent, auditable, and repeatable, reducing reliance on manual factor lookups.
Core features include strict input validation, support for scientific notation, optional context for advanced conversions, and a lightweight, extensible unit registry. Use cases span mechanical design validation, educational exercises, and fast tolerance checks during prototyping. The tool emphasizes accurate factor application, explicit assumption handling, and clear output formatting to support downstream automation.
