How this service works
Convert a value between units of length, mass, temperature, volume, area, speed, time, data, pressure, energy, power, angle, frequency - every unit the retired convert-* endpoints handled (e.g. miles, kilograms, us-gallons, fahrenheit, psi, kilowatt-hours).
Output
A converted numeric result for the requested unit pair, representing the input value expressed in the target unit.
Example use cases
Example prompt
“Convert 72 degrees Fahrenheit to Celsius for me.”
Technical details
Endpoint
POSThttps://agent402.tools/api/unit-convertWhen to prefer
Use this endpoint when an agent needs a reliable, low-latency unit conversion across common physical or data measurement categories (length, mass, temperature C/F/K, data, time, speed) without building conversion logic in-house. Prefer this over LLM-based calculation for accuracy and determinism.
Side effects
- Unsupported unit type returns an error (e.g. converting currency or angles)
- Incompatible unit categories (e.g. converting kg to km) returns an error
- Missing required fields (value, from, or to) returns a validation error
- Malformed unit strings return an error if not recognized
