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 and unit (electronvolt), the converted value in joules (IEEE-754 double precision), and metadata fields including the dimension ('energy') and precision label.
Example use cases
Particle physics energy conversion
“I have a photon energy of 2.5 electronvolts — what is that in joules?”
Scientific paper unit normalization
“My dataset has energy values in electronvolts like 500 eV and 1200 eV — can you convert those to joules so everything is in SI units?”
Educational physics problem check
“For a homework problem, I need to know how many joules correspond to 0.511 million electronvolts (the electron rest mass energy) — can you convert that for me?”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/electronvolt-to-joule?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, programmatic electronvolt-to-joule conversion with IEEE-754 double precision, especially in agent pipelines that handle physics, chemistry, or material science data requiring SI energy units. Prefer it over manual calculation or general LLM reasoning when numerical precision is critical.
Side effects
- Missing or non-numeric 'value' query parameter returns a validation error
- Negative values are rejected (minimum is 0 per schema)
- Values exceeding 1e+100 are out of range and rejected
- Non-GET HTTP methods may return 405 Method Not Allowed
- Payment not fulfilled (x402) results in 402 Payment Required before conversion is performed
