How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object containing the original value in pounds, the converted value in stones (IEEE-754 double precision), the source and target unit labels ('pound' and 'stone'), and the measurement dimension ('mass').
Example use cases
Body weight unit conversion
“I weigh 210 pounds — can you tell me what that is in stone? My UK doctor uses stone and I always forget the conversion.”
Fitness app metric display
“My app shows user weight as 154.5 pounds, but I need to display it in stone for UK users. What's the stone equivalent?”
Shipping weight record conversion
“I have a package listed as 62 pounds — convert that to stone for me please.”
