Aṅgula (from Sanskrit अङ्गुल aṅgula - 'a finger; the thumb; a finger's breadth') is a measure equal to eight barley-corns, twelve aṅgulas making a Vitasti or span, and twenty-four a Hasta or Cubit. 108 Angulam makes a 'Dhanusha'. These measurements are claimed to have been used since Indus Valley civilization and that these were used for the construction of Taj Mahal also.
One Aṅgula is believed to be approximately equal to 3/4 Inch or 1.9 centimeters.
