Why 2240 is special

Three different tons are in use: the long ton of 2,240 lb, the US short ton of 2,000 lb, and the metric tonne of 1,000 kg — about 2,205 lb. Shipping and commodity figures are frequently misread because the unit is stated as 'tons' without saying which.

Read as powers of two: 2,048 + 128 + 64 = 2,240.

In historical numeral systems

Egyptian

2 lotuses, 2 coils of rope, 4 hobbles

2 × 1,000 + 2 × 100 + 4 × 10 = 2,240. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

3 corner wedges + 7 vertical wedges (sixties place), 2 corner wedges (units place)

37 × 60 + 20 = 2240. Places are separated by a space on the tablet, with the higher place written first.

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.
