```

Example prompt: What is 88 feet per second in kilometers per hour?

## When to prefer this

Use this endpoint when you need a quick, deterministic unit conversion from feet per second to kilometers per hour without implementing the math locally. Ideal for agents processing speed data from US imperial sources that need to be displayed or compared in metric units.

## Known failure modes

- Missing 'value' query parameter returns an error
- Non-numeric or malformed value causes a 400 bad request
- Very large or very small float values may cause precision issues
- Network timeout or service unavailability returns 5xx

## How this service works

Convert feet per second to kilometers per hour (speed). Pass ?value=N.

## Output

A numeric value representing the equivalent speed in kilometers per hour, converted from the provided feet-per-second input.
