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 with the original value and unit (from: 'meter-per-second'), the target unit (to: 'kilometer-per-hour'), the converted numeric result, the dimension label ('speed'), and the precision guarantee (IEEE-754 double).
Example use cases
Weather wind speed display conversion
“The weather API gives me wind speed as 15.3 meters per second — can you convert that to kilometers per hour so I can show it in a more readable format?”
Vehicle telemetry unit normalization
“Our car sensor data reports speed in meters per second, currently reading 22.5 m/s — convert that to km/h for the dashboard display.”
Physics homework speed check
“I need to check my answer: what is 9.8 meters per second expressed in kilometers per hour?”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/speed/meter-per-second-to-kilometer-per-hour?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a reliable, pay-per-call, precision-guaranteed numeric conversion from m/s to km/h without running the arithmetic yourself — especially useful in agentic pipelines where consistent IEEE-754 double precision output and a structured JSON response (with metadata fields) are required, or when integrating with x402 micropayment workflows.
Side effects
- Missing or non-numeric 'value' query parameter returns a 4xx error
- Negative input values may be rejected (schema enforces minimum: 0)
- Values exceeding 1e+100 are rejected by schema validation
- Payment not provided or insufficient USDC triggers 402 Payment Required
- Cloudflare Worker cold start or quota exhaustion may cause 5xx errors
