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 (watt-hour), the converted value in joules, the dimension label ('energy'), and the precision standard used (IEEE-754 double). Example: {"from":"watt-hour","to":"joule","value":123.45,"converted":444420,"dimension":"energy","precision":"IEEE-754 double"}.
Example use cases
Battery capacity in joules
“I have a battery rated at 500 watt-hours — what's that in joules?”
Solar panel output conversion
“My solar panel produced 2.75 watt-hours today; convert that to joules so I can plug it into my physics simulation.”
Appliance energy usage audit
“An appliance used 0.85 watt-hours in an hour — can you tell me how many joules that is?”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/watt-hour-to-joule?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, precise, machine-readable watt-hour to joule conversion via a simple GET request with a numeric parameter. Prefer it over client-side calculation when you need a guaranteed IEEE-754 double result within a pay-per-call pipeline, or when building an agent workflow that already uses x402 micropayment infrastructure.
Side effects
- Missing or non-numeric 'value' query parameter returns a validation error
- Negative values are rejected (minimum is 0)
- Values exceeding 1e+100 are rejected by schema validation
- Non-GET HTTP methods return 405 or schema error
- Network or Cloudflare Worker cold-start timeout on rare occasions
