Where 4,184 fits
Why 4,184 is special
There are two calories. The small one heats a gram of water by a degree; the food one is a thousand of those and is properly a kilocalorie. Labels almost everywhere mean the large one whichever word they print, which is why a daily figure of 2,000 is survivable rather than instantly fatal.

4 × 1,000 + 1 × 100 + 8 × 10 + 4 × 1 = 4,184. 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.

Science
There are 4184 joules in a thermochemical kilocalorie. The calorie on a food label is this one — a kilocalorie, a thousand of the calorie used in physics. The capital C that once distinguished them has been abandoned almost everywhere, which is why energy figures on packaging are given in both units.
