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 and unit ('watt-hour'), the converted value in BTU as an IEEE-754 double-precision float, the target unit ('btu'), the energy dimension label, and a precision descriptor. Example: {from: 'watt-hour', to: 'btu', value: 123.45, converted: 421.228..., dimension: 'energy', precision: 'IEEE-754 double'}.
Example use cases
HVAC system energy audit
“I need to know how many BTU are in 500 watt-hours of energy so I can compare my electric heater output to the specs on this gas furnace.”
Physics homework unit conversion
“Can you convert 75 watt-hours to BTU? I need to express my answer in BTU for this thermodynamics problem.”
Appliance energy comparison
“My air conditioner uses 1200 watt-hours per hour — what's that in BTU so I can compare it against the BTU rating on the product label?”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/watt-hour-to-btu?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, programmatic, high-precision watt-hour to BTU conversion without running local arithmetic — particularly useful in energy auditing, HVAC comparison, or physics workflows where IEEE-754 double precision and structured JSON output are important. It is a paid micro-API ($0.001 USDC), so prefer it in automated agent pipelines where reliability and a machine-readable response format matter more than zero cost.
Side effects
- Missing required 'value' query parameter returns an error
- Negative value rejected (minimum 0 enforced by schema)
- Value exceeding 1e+100 rejected by schema validation
- Non-numeric 'value' parameter causes validation failure
- Payment not provided or insufficient USDC balance causes 402 Payment Required
