The number keeps its meaning.
How certain is the boundary?
This is a useful typical scale, not a claim that every example has exactly the same dimension.
What the engine actually divides
Vastoscope compares the SI value in metres for this reef-system extent. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.
Familiar scale bridges

something to stand beside.
These anchors are selected by logarithmic proximity from familiar human, engineered, planetary and cosmic references.

Evidence trail
Where this scale comes from.
Vastoscope keeps the displayed number separate from its measurement type and certainty. Representative and model-dependent values are intentionally labelled instead of presented as exact edges.
