Where 4700 fits
Why 4700 is special
Marketed as 4.7 GB, it reports as roughly 4.38 GB on a computer — the same decimal-versus-binary discrepancy that makes hard drives look smaller than the box claims. Seven times a CD's capacity was what made feature films on disc practical.

In historical numeral systems
Egyptian
4 lotuses, 7 coils of rope
4 × 1,000 + 7 × 100 = 4,700. 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.
