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 (mile-per-hour), the converted value in foot-per-second, the dimension (speed), and precision level (IEEE-754 double). Example: {from: 'mile-per-hour', to: 'foot-per-second', value: 123.45, converted: 181.06, dimension: 'speed', precision: 'IEEE-754 double'}.
Example use cases
Physics homework speed conversion
“I need to convert 60 miles per hour to feet per second for a kinematics problem — can you do that for me?”
Sports analytics velocity calculation
“A baseball pitch was clocked at 95 mph — what is that in feet per second?”
Engineering simulation unit normalization
“My sensor reports vehicle speed as 45 mph but my simulation needs feet per second — can you convert that?”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/speed/mile-per-hour-to-foot-per-second?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, precise programmatic conversion from miles per hour to feet per second, especially in physics, engineering, or sports analytics workflows that require IEEE-754 double precision and a structured JSON response. Prefer it over manual calculation or general-purpose math tools when you need a reliable, consistent API call with a well-defined schema.
Side effects
- Missing or non-numeric 'value' query parameter returns a validation error
- Negative value rejected (minimum is 0)
- Extremely large values (beyond 1e+100) are out of bounds
- Payment not provided or insufficient USDC triggers 402 Payment Required
- Non-GET/HEAD/DELETE HTTP methods return method-not-allowed error
