Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| convertA | Convert a value from one unit to another. Returns the converted value with conversion factor, or a structured error if the units are dimensionally incompatible. |
| check_compatibilityB | Check if two units are dimensionally compatible (i.e., can be converted). Returns whether the units share the same physical dimension. |
| parse_quantityA | Parse a quantity string into structured components. Accepts expressions like '100 mg/L' or '9.81 m/s²'. Returns the magnitude, units, dimensionality, and SI equivalent. |
| list_compatible_unitsA | List all units compatible with the given unit. Returns every canonical unit name that shares the same physical dimension, including imperial and US customary units. |
| simplifyA | Simplify a unit expression to its most compact form. Adjusts prefixes (e.g., 1000 Pa → 1 kPa) and reduces named units. Also provides the base SI representation. |
