How this service works
Unit conversion — Convert between units (length, mass, volume, speed, area, data, time, pressure, energy, temperature, angle).
Output
Returns the converted numeric value in the target unit, along with the conversion factor used. The response confirms the source value, source unit, target unit, and computed result.
Example use cases
Recipe ingredient scaling
“I have a recipe that calls for 2 cups of flour, but my scale only measures grams — can you convert 2 cups to grams? Actually, let's say 500 milliliters to grams for water.”
International driving speed reference
“The speed limit sign here says 110 km/h — how fast is that in miles per hour?”
Data storage capacity planning
“I need to know how many gigabytes are in 2 terabytes — can you convert that for me?”

Endpoint
GEThttps://mcpfax-utility.bowling-anthony.workers.dev/v1/unit-convertWhen to prefer
Choose this endpoint when you need a quick, accurate unit conversion across common physical and digital measurement categories without setting up a local math library. It is especially useful in agent workflows where users reference mixed unit systems (metric vs imperial) or need cross-domain conversions like data storage or energy units.
Side effects
- Unsupported unit category or unit name returns an error indicating the unit is not recognized
- Incompatible unit types (e.g. converting length to mass) return an error about mismatched categories
- Missing required fields (value, from_unit, to_unit) result in a validation error
- Extreme numeric values may produce precision or overflow errors
