Scientific tools
Calculate, convert, solve and inspect with the model visible beside the answer. Every production scientific tool keeps its inputs, assumptions and conceptual context within reach.
Production tools
These tools are backed by published STEMORIA scientific entities. Their calculation logic is deterministic and remains connected to its scientific context.

calculator
01Calculate pressure from volume, amount of substance, and thermodynamic temperature using the ideal gas law.
Calculators
Deterministic scientific calculations with the governing quantities kept visible.
10Converters
Move between representations and units without hiding what the conversion means.
02Solvers
Structure multi-step scientific problems around inputs, constraints and interpretable outputs.
01Design rule
A STEMORIA tool should expose the scientific quantities, model boundary and connection to learning. Future tools inherit this workstation shell instead of becoming isolated calculators.
