How this service works
Unit conversion for length, mass, volume, and temperature using exact conversion factors (temperature uses the correct affine formulas, not simple multiplication).
Output
Returns the converted numeric value in the target unit, computed using exact conversion factors. For temperature, uses the correct affine transformation (e.g., °F to °C: (F−32)×5/9) rather than simple multiplication, ensuring precision across all supported categories (length, mass, volume, temperature).
Example use cases
Recipe ingredient unit conversion
“I have a recipe that calls for 250 milliliters of milk but I only have measuring cups — can you convert that to cups for me?”
Body weight in different units
“My doctor's scale shows 82 kilograms — what does that come out to in pounds?”
International road distance conversion
“A road sign says the next city is 45 kilometers away. How many miles is that?”

Endpoint
POSThttps://ppu43fkyhimq5fiqpmo42eh5ri0yypid.lambda-url.us-east-1.on.aws/unitConvert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need precise, mathematically correct unit conversions — especially for temperature, where naive multiplication gives wrong results. Prefer it over general-purpose LLM computation when exactness matters and you want a reliable, deterministic answer for length, mass, volume, or temperature conversions.
Side effects
- Unsupported unit string for the given category returns an error
- Mismatched category and units (e.g. passing 'kg' with category 'length') returns an error
- Missing required fields (value, from, to, category) returns a validation error
- Incompatible unit pair conversion (e.g. mass to length) returns an error
