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 and unit ('long-ton'), the converted numeric result in stones ('converted'), the target unit name ('stone'), the dimension ('mass'), and the precision level ('IEEE-754 double').
Example use cases
Shipping freight weight reconciliation
“I have a cargo shipment listed as 12.5 long tons — what is that in stones?”
Historical UK weight record lookup
“A Victorian-era record lists a load as 0.85 long tons; can you tell me what that is in stones so I can compare it to modern measurements?”
Engineering spec unit normalisation
“Our supplier sent a material spec showing 47 long tons — I need that converted to stones for our British engineering report.”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/mass/long-ton-to-stone?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, pay-per-call conversion from imperial long tons to stones with well-defined IEEE-754 precision guarantees and no setup required. Ideal for agents that occasionally need this specific unit pair without embedding a full unit-conversion library.
Side effects
- Missing or non-numeric 'value' query parameter returns a validation error
- Negative values or values exceeding 1e+100 are rejected by schema validation
- Non-GET HTTP methods are rejected
- Payment not provided or insufficient USDC balance results in HTTP 402 response
- Extremely large numbers may produce floating-point rounding artifacts inherent to IEEE-754 double precision
