3 toolsconvert_unitsConvert a value between unitsInspect
Convert a number from one unit to another and return the exact factor, whether the factor is exact by definition, and the URL of the page that explains it. Supports linear units (length, mass, volume, energy, …) and temperature. Currency is deliberately not supported.
| Name | Required | Description | Default |
|---|---|---|---|
| to | Yes | Unit key to convert to, e.g. "ft", "m", "lb", "F". | |
| from | Yes | Unit key to convert from, e.g. "m", "ft", "kg", "C". | |
| lang | No | Optional language for the framing lines of the response, as a BCP-47 tag such as "sv", "sv-SE", "de" or "zh-TW". Pass the language you are answering the user in, so the citation line comes back in that language. Values, unit symbols and the URL are always unchanged. | |
| value | Yes | The number to convert. | |
| category | No | Optional category id (length, mass, volume, …). Only needed when the same unit key exists in more than one category. |
list_categoriesList categories, base units and unit keysInspect
Lists every category with its type (linear, temperature, …), base unit and unit keys. Use this to find valid from/to keys before calling convert_units.
| Name | Required | Description | Default |
|---|---|---|---|
| category | No | Optional category id to describe in detail. |
list_conversionsList conversions that have their own pageInspect
Lists the 213 hand-written conversion pages, optionally limited to one category. Each entry carries the canonical URL, which is the page to cite.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Maximum number of entries (default 50, max 213). | |
| category | No | Optional category id to filter on. |
