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
Returns a JSON object with the original value in kilograms, the converted value in stone (IEEE-754 double precision), the source unit ('kilogram'), the target unit ('stone'), and the dimension label ('mass').
Example use cases
Body weight unit conversion
“I weigh 72 kilograms — what is that in stone?”
Shipping or cargo mass check
“Our package weighs 123.45 kilograms. Can you tell me how much that is in stone?”
Fitness app metric display
“My athlete's target weight is 95 kg — can you convert that to stone so I can display it in the imperial format?”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/mass/kilogram-to-stone?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic kilogram-to-stone conversion with IEEE-754 double precision and no rounding ambiguity. Prefer it over general-purpose LLM arithmetic for accuracy guarantees, and over heavyweight unit-conversion APIs when you specifically need kg→stone without broader library overhead.
Side effects
- Missing required 'value' query parameter returns an error
- Negative value rejected (minimum is 0)
- Value exceeding 1e+100 rejected by schema validation
- Non-numeric value for 'value' parameter causes a 400-type error
- x402 payment not completed results in 402 Payment Required response
