Where 327 fits
Why 327 is special
A wood fire reaches it, which is why lead was among the first metals worked and why it ended up in pipes, paint and fuel long before its toxicity was understood or acted upon.
Same number, different meanings
How 327 is understood across different contexts — never implying one meaning because of another.
- Mathematics
A wood fire reaches it, which is why lead was among the first metals worked and why it ended up in pipes, paint and fuel long before its toxicity was understood or acted upon.
- Science
The melting point of lead is 327 degrees Celsius (worldwide, at standard pressure). Within reach of a domestic fire, which is why lead was the metal of choice for type, pipes and shot for centuries before anyone could reach iron's temperature reliably.
- Technology & computing
CWE-327 is use of a broken or risky cryptographic algorithm. It captures continued use of primitives such as MD5 and single DES after published attacks made them unsuitable.

Read as powers of two: 256 + 64 + 4 + 2 + 1 = 327.
In historical numeral systems
Egyptian
3 coils of rope, 2 hobbles, 7 strokes
3 × 100 + 2 × 10 + 7 × 1 = 327. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 vertical wedges (sixties place), 2 corner wedges + 7 vertical wedges (units place)
5 × 60 + 27 = 327. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then kappa, then zeta, marked as a numeral
tau-kappa-zeta + keraia
tau + kappa + zeta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then kaf, then zayin
shin-kaf-zayin
shin (300) + kaf (20) + zayin (7) = 327, written in descending order.
Maya
3 bars + 1 dot (upper, twenties place) over 1 bar + 2 dots (lower, units place)
16 × 20 + 7 = 327. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.

Related numbers & connections
Lead melts at about 327 degrees, low enough for a wood fire, and tungsten at 3,422, the highest of any metal. The span between them is most of what determines which metals ancient societies could use.

DocumentedScienceGeography: worldwide, at standard pressureLead melts low enough to be cast over an ordinary fire, which made it one of the earliest metals in general use. Its accessibility is a substantial part of why it spread into plumbing, pigment and petrol before the health consequences were addressed.
