Perform unit-aware engineering calculations using CalcsLive articles. Automatically handles unit conversions and dependency calculations. Example: Calculate hydro power with flow rate 150 m³/s and head 25m. Returns calculated outputs with values and units.

Run stateless unit-aware calculations from Physical Quantity (PQ) script definitions. Define inputs and outputs as PQ objects with symbols, values, units, and expressions. No article creation needed - fully stateless. Automatically handles unit conversions, dependency graphs, and Greek letters. Example: Calculate circle area from radius using expression 'pi * r^2'.

Discover available inputs and outputs for a calculation article. Use this before calculate to understand what parameters are available and their units. Returns article metadata including all input/output PQs with descriptions, units, and available unit options.
