How this service works
A crossing for play, feeling, language, science and computation — creating states that do not have names yet.
Output
Returns a JSON object with a 'data' array containing the conversion result(s), a 'count' integer, and an 'attribution' string crediting the underlying unit database or license source.
Example use cases
Recipe unit conversion for cooking
“I need to convert 2.5 cups to milliliters — from 'cup_us' to 'mL'.”
Scientific data unit normalization
“Convert 101325 pascals to atmospheres, from 'Pa' to 'atm', so I can normalize my pressure readings.”
Distance conversion for travel planning
“How many miles is 42.195 kilometers? Convert from 'km' to '[mi_i]' please.”
Technical details
Endpoint
GEThttps://api.lilambd.com/units/convert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic unit conversion with support for UCUM (Unified Code for Units of Measure) identifiers alongside common symbols and names — particularly useful for scientific, medical, or engineering contexts where standard unit codes matter. It is a paid microservice suitable for agent workflows needing reliable, attributed conversions at low per-call cost.
Side effects
- Unknown or misspelled unit identifiers in 'from' or 'to' fields returning empty data array
- Non-numeric value in the 'value' parameter causing parse errors
- Incompatible unit types (e.g. length to mass) returning no valid conversion
- Missing required query parameters returning a 400-level error
- Payment failure via x402 protocol preventing access
