Comment[edit]

Correct the IPA: /ˈsɪ.sɚ.oʊ/.

Not sure what's going on there currently (rhotacized e-schwa?, strange attempt at showing an American diphthonged O??) -- but there definitely should be an English R starting the last syllable...

Had to remove this on metric standardization...[edit]

I had to remove this statement on metric standardization:

"In 1973, the cicero was metrically standardized at 4.5 mm."


Compare the different, more complex (and highly confusing) info on French points in:

Point (typography)


This article still has metric equivalents in the right sidebar that I'm leaving -- should be researched and corrected as needed -- looks like there is no one standard though.

BIG QUESTION what is the cicero size in modern computer page layout software? For example Quark, etc. can use ciceros I believe.

From Donald Knuth's TeXbook:

  • pt point
  • pc pica (1 pc = 12 pt)
  • in inch (1 in = 72.27 pt)
  • bp big point (72 bp = 1 in)
  • cm centimeter (2.54 cm = 1 in)
  • mm millimeter (10 mm = 1 cm)
  • dd didot point (1157 dd = 1238 pt)
  • cc cicero (1 cc = 12 dd)
  • sp scaled point (65536 sp = 1 pt)

From that we get one cicero = 12 dd = 12 * 1238 / 1157 pt = 12 * 1238 / 1157 / 72.27 in = 12 * 1238 / 1157 / 72.27 * 2.54 cm ~ 0.4513 cm. The article states one cicero is exactly 0.45cm. I have no idea if that is correct in any interpretation. --82.128.250.221 (talk) 00:50, 7 July 2014 (UTC)

From the pdfTeX manual: "Two new units of measure were introduced in pdfTEX 1.30.0: the new Didot (1 nd = 0.375 mm) and the new Cicero (1 nc = 12 nd) (the former was proposed by ISO in 1975).". So I guess that as far as modern is TeX is concerned a 4.5mm cicero does exist. --82.128.250.221 (talk) 23:29, 12 July 2014 (UTC)
