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 joules, the converted value in watt-hours (IEEE-754 double precision), the source and target unit labels ('joule' and 'watt-hour'), and the dimension type ('energy').
Example use cases
Battery capacity calculation
“I have a battery that stores 18000 joules of energy — how many watt-hours is that?”
Physics homework energy conversion
“Can you convert 500 joules to watt-hours? I need the precise IEEE-754 double result for my lab report.”
IoT sensor data normalization
“My sensor is reporting energy in joules — can you convert 9500 joules to watt-hours so I can log it in Wh units?”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/joule-to-watt-hour?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, programmatic joule-to-watt-hour conversion with well-defined IEEE-754 double precision output and a stable JSON schema. It is ideal for automated pipelines, IoT data normalization, or physics/engineering calculations where consistent output structure matters. Prefer it over manual formulas when you need machine-readable labels and dimension metadata alongside the converted value.
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 method-not-allowed errors
- Network or worker cold-start latency may occasionally increase response time
