Where 80,000 fits
Why 80,000 is special
It is the standard that says a kilobyte is 1,000 bytes and a kibibyte is 1,024, a distinction storage manufacturers adopted and operating systems largely did not.

8 × 10,000 = 80,000. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
