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, the source unit ('electronvolt'), the target unit ('megajoule'), the converted numeric result, the energy dimension label, and the precision standard (IEEE-754 double).
Example use cases
Particle physics energy analysis
“I'm working on a particle physics calculation — can you convert 9.11e-31 electronvolts to megajoules so I can compare it against macro-scale energy figures?”
Scientific paper unit normalization
“I need to express 6.242e18 electronvolts in megajoules for a paper I'm writing — can you do that conversion for me?”
Educational energy scale comparison
“My student asked how many megajoules correspond to 1 electronvolt — can you give me the precise converted value?”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/electronvolt-to-megajoule?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, paid, on-demand electronvolt-to-megajoule conversion with IEEE-754 double precision guarantees, particularly in scientific or physics workflows where accuracy matters. It is purpose-built for this specific unit pair and returns structured JSON with dimension metadata, making it suitable for automated pipelines.
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
- Payment not included or insufficient USDC triggers x402 payment-required response
