The marked defined curd diameter is calibrated. Unmeasured illustration details are representative.

Geoduck

Defined shell length: 17 cm; defined specimen; range 12 cm–22 cm.

A defined Pacific geoduck with a 17 cm shell and 1.2 kg live mass. The long siphon can extend far beyond the shell and is shown for identity, but shell length is the calibrated span.

Why this measurement?

Why we use 18 cm

We compare the curd diameter of a cauliflower head. This is an illustrative comparison value, not a claim that every example is the same. The recorded range is 14 cm to 24 cm.

A defined trimmed white cauliflower head 18 cm across and 1 kg. Cultivar and growing conditions vary; the compact edible curd defines diameter, while leaves and cut stalk are excluded.

The marked horizontal span follows the measured feature, not the edges of the image. How calibrated comparisons work →
