Where 760 fits
Why 760 is special
The figure comes from Torricelli's barometer, where the atmosphere supports a mercury column about 760 mm tall. The unit named after him, the torr, is one millimetre of that column, and it is still the working unit in vacuum systems and parts of medicine.
Same number, different meanings
How 760 is understood across different contexts — never implying one meaning because of another.
- Mathematics
The figure comes from Torricelli's barometer, where the atmosphere supports a mercury column about 760 mm tall. The unit named after him, the torr, is one millimetre of that column, and it is still the working unit in vacuum systems and parts of medicine.
- Technology & computing
The torr is defined by division: exactly one seven-hundred-and-sixtieth of the standard atmosphere, itself fixed at exactly 101,325 pascals. Its near-twin is defined physically instead, from a stated fluid density and a standard gravity. The two therefore agree only to about one part in seven million — a discrepancy that is invisible at a weather station and real in a metrology laboratory, which is why both survive with values a reader would assume were the same.
- Science
There are 760 millimetres of mercury in one standard atmosphere (worldwide, the conventional barometric figure). The unit survives in medicine, where blood pressure is still reported in millimetres of mercury, long after mercury columns stopped being used to measure it.

In historical numeral systems
Egyptian
7 coils of rope, 6 hobbles
7 × 100 + 6 × 10 = 760. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 2 vertical wedges (sixties place), 4 corner wedges (units place)
12 × 60 + 40 = 760. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then xi, marked as a numeral
psi-xi + keraia
psi + xi written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then shin, then samekh
tav-shin-samekh
tav (400) + shin (300) + samekh (60) = 760, written in descending order.
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.

The same standard sea-level pressure in two units — 1,013 hPa and 760 mm of mercury. Meteorology uses the first and medicine still largely uses the second.

DocumentedScienceGeography: worldwide, the conventional barometric figureStandard atmospheric pressure supports a column of mercury about 760 mm tall, which is what Torricelli's barometer measures. The torr — one millimetre of that column — remains the working unit in vacuum engineering and in parts of clinical medicine, where blood pressure is still quoted in mmHg.
