This is a pictograph of a measuring rod. There are nine spaces which gives us nine units of measurement. However, you should note that the marks between the spaces are diagonal rather than horizontal. This indicates that the measurement is estimated rather than precise. Hence, the translation for this Indus sign is: roughly nine units.
