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 in watt-hours, the converted result in kilocalories (IEEE-754 double precision), the source and target unit labels ('watt-hour' and 'kilocalorie'), and the dimension category ('energy').
Example use cases
Battery energy in food calories
“I have a 500 watt-hour battery pack — how many kilocalories of energy does that represent?”
Solar panel daily output conversion
“My solar panel produced 3,200 watt-hours today. Can you tell me what that is in kilocalories?”
Appliance energy cost in kcal
“A microwave used 0.75 watt-hours heating my lunch. Convert that to kilocalories so I can compare it to the food's caloric content.”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/watt-hour-to-kilocalorie?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, reliable, IEEE-754 precise conversion from watt-hours to kilocalories specifically, without needing to build or host your own conversion logic. It is ideal for agents automating energy analytics, nutrition comparisons, or physics calculations where accuracy matters and the $0.001 per-call cost is acceptable.
Side effects
- Missing required 'value' query parameter returns an error
- Negative input value rejected (minimum is 0)
- Non-numeric value for 'value' parameter causes a validation error
- Extremely large values near 1e+100 may hit floating-point precision limits
- Payment failure or insufficient USDC balance returns HTTP 402
