Exact unit conversion with the factor and a citable page URL. Answers in your language.
Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
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.
Unit key to convert to, e.g. "ft", "m", "lb", "F".
Unit key to convert from, e.g. "m", "ft", "kg", "C".
The number to convert.
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.
Optional category id (length, mass, volume, …). Only needed when the same unit key exists in more than one category.
