Unit definitions
A plain-language summary of the seven SI base units, common derived units and why unit categories matter before converting values.
- Length measures distance and uses meters as the base unit in Convematik.
- Mass measures quantity of matter and uses kilograms as the base unit.
- Temperature uses scale formulas rather than simple multiplication.
- Area and volume are derived measurements and must stay inside their own categories.
- Speed, energy, power, pressure and data use category-specific bases for API consistency.
