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 containing the original value in kilocalories, the converted value in kilojoules (IEEE-754 double precision), the source unit ('kilocalorie'), the target unit ('kilojoule'), and a dimension label ('energy'). Example: 123.45 kcal converts to approximately 516.51 kJ.
Example use cases
Nutrition label energy conversion
“I have a food item listed as 450 kcal on its nutrition label — what is that in kilojoules?”
Fitness app metric translation
“My workout tracker says I burned 320 kilocalories. Can you convert that to kilojoules so I can log it in my European fitness app?”
Scientific report unit standardization
“I need to express 1800 thermochemical kilocalories in kilojoules for my research report — can you give me the precise converted value?”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/kilocalorie-to-kilojoule?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, programmatic kilocalorie-to-kilojoule conversion without relying on a general-purpose calculator or LLM approximation. Ideal for agents processing nutrition data, scientific computations, or fitness metrics that require deterministic IEEE-754 double-precision results. Prefer this over a formula-based approximation when auditability and exact numeric output are required.
Side effects
- Missing or invalid 'value' query parameter returns an error
- Negative input values are rejected (minimum: 0)
- Values exceeding 1e+100 are rejected by schema validation
- Non-numeric value parameter causes a validation error
- Network or worker availability issues may return 5xx errors
