# Length, area and volume conversion
# Scope: Length, square area and cube volume conversions.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

length = 0.3 m

millimetres := length [mm]
area := length^2 [cm^2]
volume := length^3 [L]

check length positive: length > 0 m

scenario alternative: length = 0.24 m
