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 and unit (kilometer-per-hour), the converted value in knots (IEEE-754 double precision float), the target unit label (knot), and the dimension (speed). Example: converting 123.45 km/h yields approximately 66.66 knots.
Example use cases
Maritime vessel speed logging
“Our ship is cruising at 28 km/h — what's that speed in knots so I can log it in the nautical record?”
Aviation wind speed briefing
“The reported wind speed is 65 km/h. Can you convert that to knots so our pilot can use it in the flight plan?”
Weather forecast unit conversion
“The forecast shows gusts of 110 km/h — what's that in knots for the marine weather bulletin?”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/speed/kilometer-per-hour-to-knot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, programmatic km/h to knots conversion, particularly in aviation, maritime, or meteorological contexts where knot units are standard. It is lightweight, idempotent, and inexpensive ($0.001 USDC), making it ideal for high-frequency agent pipelines that need reliable unit conversion without building custom math logic.
Side effects
- Missing or non-numeric 'value' query parameter returns a validation error
- Negative value rejected (minimum is 0)
- Value exceeding 1e+100 rejected by schema maximum constraint
- Non-GET HTTP method returns method-not-allowed error
- Network or Cloudflare Worker downtime results in 5xx response
