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 (mile-per-hour), the converted value in kilometer-per-hour computed with IEEE-754 double precision, the dimension (speed), and metadata about the conversion direction.
Example use cases
Metric speed display for US drivers abroad
“I'm driving in Canada where speed limits are in km/h — can you tell me what 55 mph is in kilometers per hour so I know how fast to go?”
Athletics performance unit conversion
“My runner's pace was recorded as 8.5 miles per hour — what is that in kilometers per hour for the international leaderboard?”
Engineering spec conversion
“Our vehicle spec sheet lists top speed as 120 miles per hour. What's the equivalent in km/h for the European market version of the document?”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/speed/mile-per-hour-to-kilometer-per-hour?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, precise, paid-per-call mph-to-km/h conversion with a structured JSON response including dimension and precision metadata. Prefer it over general-purpose math tools when you need guaranteed IEEE-754 double precision and a machine-readable unit conversion record.
Side effects
- Missing required 'value' query parameter returns an error
- Negative speed value rejected (minimum is 0)
- Extremely large values beyond 1e+100 are rejected
- Non-numeric value parameter causes a validation error
- Network timeout on the Cloudflare Worker edge node
