# Pressure conversion
# Scope: Gauge pressure plus an explicitly supplied atmospheric reference.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

gauge = 2 bar
atmosphere = 101325 Pa

absolute := gauge + atmosphere [Pa]
psi := absolute [psi]

check absolute pressure positive: absolute > 0 Pa

scenario alternative: gauge = 1.6 bar
