Where 10,994 fits
Why 10,994 is special
The figure is disputed: independent surveys since 1951 have produced values from about 10,924 to 11,034 metres, and the uncertainty is larger than most published statements suggest. More people have walked on the Moon than have reached the bottom.
Same number, different meanings

- History
Jacques Piccard and Don Walsh took the bathyscaphe Trieste to the bottom of Challenger Deep in January 1960, before any survey had established how deep it was. A window cracked on the way down and they stayed about twenty minutes. No one returned for fifty-two years, and the depth figures have been revised repeatedly since — the descent came first and the measurement afterwards, which is the reverse of the usual order.
- Geography
Surveys of Challenger Deep since 1951 have produced depths from roughly 10,924 to 11,034 metres, and the spread is wider than most single published figures suggest. More people have walked on the Moon than have reached the bottom.

1 × 10,000 + 9 × 100 + 9 × 10 + 4 × 1 = 10,994. 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.
