Choose this endpoint when you need a fast, inexpensive, and reliable unit conversion in a tutoring or educational context, especially for common length (km/mi/m/ft), mass (kg/g/lb/oz), volume (L/mL/cup/gal), or temperature (°C/°F/K) units and do not need a full-featured math engine or multi-step calculation.

## Known failure modes

- Unsupported unit pair returns an error (e.g. mixing incompatible categories like length to temperature)
- Invalid or missing 'value' field causes a validation error
- Unrecognized unit string in 'from_unit' or 'to_unit' returns an error
