How this service works
Convert a value between units of length, area, volume, mass, energy (kWh, MWh, BTU, GJ), power, pressure, temperature, speed, data size, time and compound units like kg/m^3 or mpg. Exact, no lookup tables to maintain.
Output
Returns the converted numeric value in the target unit, computed exactly without lookup tables, supporting compound units like kg/m³ and mpg.
Example use cases
Energy billing unit conversion
“I have a battery storage system that produced 4.5 MWh this month — can you convert that to GJ so I can put it in our report?”
International recipe scaling
“This recipe calls for 2 pounds of flour and 3 cups of milk, but I need everything in grams and liters — can you convert those for me?”
Engineering pressure unit check
“Our sensor is reading 145 psi — what is that in bar so I can compare it to the European spec sheet?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/util/units?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need exact, deterministic unit conversions across a wide variety of physical and engineering domains including compound units like mpg or kg/m³. Prefer this over generic math tools or LLM-based conversion when precision matters and you need a reliable, no-lookup-table calculation.
Side effects
- Unrecognized unit string returns an error (e.g. typo in from_unit or to_unit)
- Incompatible unit types (e.g. converting length to mass) returns a conversion error
- Missing required query parameters (value, from_unit, to_unit) returns a 400 bad request
- Extreme numeric values may produce overflow or underflow results
