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 ('knot'), the converted result in feet per second ('foot-per-second'), the dimension ('speed'), and a note that precision is IEEE-754 double. Example: {from: 'knot', to: 'foot-per-second', value: 123.45, converted: 208.36, dimension: 'speed', precision: 'IEEE-754 double'}.

Example use cases

Aviation speed crosscheck

“I need to know what 250 knots is in feet per second — can you convert that for me?”

Wind speed unit conversion

“The weather station is reporting wind at 30 knots — what's that in feet per second?”

Maritime vessel speed calculation

“Our ship is cruising at 18.5 knots; convert that to feet per second so I can use it in a physics formula.”

When to prefer

Choose this endpoint when you need a reliable, precise (IEEE-754 double) knot-to-foot-per-second conversion in a single API call with no setup, particularly in aviation, maritime, or meteorological contexts where speed unit conversion is a frequent sub-task. It is a simple pay-per-use computation endpoint with no side effects.

Side effects

Missing or non-numeric 'value' query parameter returns an error
Value below 0 or above 1e+100 is rejected by schema validation
Non-GET HTTP method returns method-not-allowed
Payment not provided or insufficient USDC triggers 402 payment required
Server-side Cloudflare Worker quota exceeded returns rate limit error
