They also had a standardized system of weights and measures, many of which are echoed two thousand years later in the Arthashastra, a manual on governance and political economy written in the third century BC. Danino calculates that the standard length used by the planners at Dholavira was 1.9 metres which is the same as the unit called dhanush (i.e. bow) used in the Arthashastra. He then shows that this unit was divided into 108 sub-units of 1.76 cm each. This fits with the 108 angulas (i.e. finger-widths) that made up a dhanush.
