How this service works
Convert any value between units: length (m/km/mi/ft/in/yd/nmi, plus Russian verst/sazhen/arshin/vershok), mass (g/kg/lb/oz/tonne, plus Russian pood/funt/zolotnik), area (m2/ft2/km2/acre/hectare) and temperature (C/F/K). Pass ?value=<n>&from=<unit>&to=<unit>. Returns the converted value and the unit category.
Output
A JSON object containing the converted numeric value and a string identifying the unit category (e.g. 'length', 'mass', 'area', 'temperature'), along with an 'ok' boolean status flag.
Example use cases
Temperature conversion for weather display
“What is 98.6 degrees Fahrenheit in Celsius?”
Historical Russian unit lookup
“How many kilograms is one pood? I'm reading an old Russian novel and need to know the weight.”
Land area unit conversion
“Convert 50 acres to hectares — I need to compare a US property listing to a European one.”

Endpoint
GEThttps://47620.xyz/x/util/convert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call unit conversion without integrating a heavy SDK. It is especially useful when dealing with historical Russian units (verst, pood, arshin, zolotnik, sazhen, funt, vershok) not found in most converters, or when you need conversion plus category labeling in a single structured JSON response.
Side effects
- Unsupported unit code returns an error or null result
- Missing required query parameters (value, from, to) cause a bad request response
- Mismatched unit categories (e.g. converting miles to kilograms) return an error
- Non-numeric value parameter causes a parse error
- Payment failure (x402) if USDC not provided
