What this measurement describes
Circumference follows a closed path around a ring or body and must not be interpreted as its diameter.

The number keeps its meaning.
How certain is the boundary?
This is an observed measurement. The displayed precision follows the cited reference and should not be read as infinite accuracy.
What the engine actually divides
Vastoscope compares the SI value in metres for this accelerator ring circumference. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.

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.
