How this service works
Convert between units: length, weight, volume, temperature, area, speed, data storage. Algorithmic — instant.
Output
Returns the converted numeric value in the requested target unit, computed algorithmically and returned instantly.
Example use cases
Recipe ingredient scaling for international cooking
“I'm making a recipe that calls for 500 grams of flour, but my kitchen scale only shows ounces. Can you convert that for me so I know exactly how much to measure out?”
International shipping dimension validation
“Our package dimensions are listed as 50 cm by 30 cm by 20 cm, but the shipping carrier needs them in inches. What should I input into their system?”
Real-time data storage capacity planning
“We're analyzing server capacity and need to know how many terabytes equal 5,000 gigabytes so I can properly size our infrastructure needs.”
Technical details
Endpoint
GEThttps://api.strale.io/x402/unit-convert?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a reliable, instant unit conversion across common measurement categories (length, weight, volume, temperature, area, speed, data storage) without needing a general-purpose calculator or external lookup. Ideal for agents that need deterministic, algorithmic results rather than LLM-estimated conversions.
Side effects
- Unsupported or misspelled unit codes return an error (e.g. unknown from_unit or to_unit)
- Incompatible unit categories (e.g. converting km to kg) return a type mismatch error
- Missing required query parameters (value, from_unit, to_unit) return a 400 bad request
- Non-numeric value input returns a validation error
