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 megajoules, the converted value in kilocalories (IEEE-754 double precision float), the source unit ('megajoule'), the destination unit ('kilocalorie'), and the energy dimension label. Example: {from: 'megajoule', to: 'kilocalorie', value: 123.45, converted: 29505.25, dimension: 'energy', precision: 'IEEE-754 double'}.
Example use cases
Nutrition energy calculation
“I have a food item with 2.5 megajoules of energy content — what is that in kilocalories so I can put it on a nutrition label?”
Physics homework unit conversion
“Can you convert 850 megajoules to kilocalories? I need the exact value for my thermodynamics assignment.”
Industrial process energy audit
“We measured 4200 megajoules of heat output from our furnace today — convert that to kilocalories so I can compare it to our efficiency benchmarks.”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/megajoule-to-kilocalorie?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, precise, single-call megajoule-to-kilocalorie conversion with no setup, libraries, or local computation required. Ideal for agents that need on-demand energy unit translation in nutrition, physics, or engineering contexts without embedding a unit-conversion library. Costs $0.001 USDC per call via x402, so suitable for occasional lookups rather than bulk batch conversions.
Side effects
- Missing or non-numeric 'value' query parameter returns a 400 error
- Negative input values rejected (minimum is 0)
- Values exceeding 1e+100 rejected as out of range
- Payment not provided or invalid x402 payment header returns 402 Payment Required
- Rate limit or quota exceeded returns 429
