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 ('electronvolt'), the converted value in kilocalories (as a floating-point number with IEEE-754 double precision), the target unit label, and the physical dimension ('energy').
Example use cases
Particle physics energy comparison
“I have a photon with energy of 2.5 electronvolts — what is that in kilocalories?”
Chemistry simulation unit normalization
“My simulation outputs energies in electronvolts; convert 0.026 eV to kilocalories so I can compare it to thermochemical data.”
Educational physics problem solver
“A student's problem gives an energy of 1000 electronvolts — what is the equivalent in kilocalories?”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/electronvolt-to-kilocalorie?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, programmatic electronvolt-to-kilocalorie conversion via a simple GET request, especially in scientific, chemistry, or physics workflows where IEEE-754 double precision is required and paying $0.001 USDC per call via x402 is acceptable.
Side effects
- Missing or non-numeric 'value' query parameter returns an error
- Negative values are rejected (minimum is 0)
- Values exceeding 1e+100 are out of range and rejected
- Non-GET HTTP methods are not accepted
