In Jain cosmology, 1 Rajju is an extremely large cosmic unit of length. A commonly cited estimate is about 2.62 × 10^21 km in the Svetambara calculation, and about 2.33 × 10^21 km in the Digambara calculation. So it is not a fixed everyday distance, but a cosmic measure. ( jainqq.org)

If you want, I can also give the full Jain distance table from angula to rajju.
