diameter

The overall outer (or rim) diameter of a round or cylindrical product — the distance across a circular section through its centre. The general headline dimension of round housewares and goods: a bowl or pot by its rim diameter (a 30 cm bowl), a bin, a plate, a lid, a wheel, a pipe's bore. A numeral with a length unit (mm / cm / m / in). Product-intrinsic, distinct from SHIPPING/package dimensions (fulfilment). This is the PRODUCT'S OWN overall diameter — kind-specific part diameters (a microwave's turntable_diameter, a slicer's blade_diameter) remain separate facts of a named part, not this general one. Where a catalogue merchandises the same product across diameter variants, that is a downstream family statement, not a Pool fact.

Diameter is a measured figure, given in millimeters or inches.

It belongs to measurement — its measurable, physical facts.
