). This term is also used as a technical unit of 

measurement in various traditional Indian sciences like mathematics, 

architecture (Vāstuśāstra), sculptural arts (Śilpaśāstra), Jyotisha 

(astronomy), and Ayurveda (

Measurement Significance

• Standard Length: An aṅgula is conventionally the breadth of the middle 
• phalanx of a finger, often equated to approximately 1.763–1.95 cm 
• (0.66–0.77 inches), although values vary depending on the period 
• and text (

• Relation to Larger Units:
  • 12 aṅgulas = 1 Vitasti (span)
  • 24 aṅgulas = 1 Hasta (cubit)
  • 108 aṅgulas = 1 Dhanusha (
