Definition
Texts define finger-based aṅgula systems, but ASI explicitly found bodily aṅgula/hasta measurements vary; architectural sources distinguish multiple aṅgula sizes.
Reference value
No universal SI value
Modern use
Modern-use scope is context-dependent; the website should follow the record's current-status and regional/system labels rather than imply universal use.
Did you know?
Excellent example of a historically real unit where body-based language does not create one exact physical standard.
