Why this measurement?

Why we use 5 cm

For comparison, this page uses defined fruit diameter. This is labelled defined specimen: an explicit comparison model rather than a claim that every example has the same value. The recorded range is 3.5 cm to 6.5 cm.

A defined medium raw plum 5 cm across and 66 g in mass. Cultivar, ripeness and growing conditions vary; stem and leaves are excluded from the fruit diameter.

The marked horizontal span follows the named feature; transparent margins and unmeasured details do not alter it. How calibrated comparisons work →
