0.204 fact. It is worth consideration which of these values may be taken as applicable in all cases. Lord Mahavira must have given one value for it. How and when this variety and values of Angula started is a problem for further research. One of the reasons for this might be the personal or literary communication gap between the scholars of different periods. This gap has vanished in this century and it is the best time for uniformity in units and their values.
When areas or volumes are to be expressed, the 2-d or 3-d units are used. The 2-d and 3-d Angula units are known as Pratarangula (PrA) and Ghanangula (GA) respectively. Their values are equal to the square and cube of the Angula unit. They are shown in Table VII.
