Why write "pc" and not "%"? Is this a common style?

[zipy124]

Its common to dis-stinguish between different types of percentage metrics like percent, percetage point and basis point as symbols for them are not commonly used. Specifically that its easier to say, a decrease from 50% to 40% would be a decrease of 10 pp, but a decrease of 20pc (%) for example.

Paradox of choice, there are too many good percent symbols:

    U+0025 % PERCENT SIGN
    U+FF05 ％ FULLWIDTH PERCENT SIGN
    U+FE6A ﹪ SMALL PERCENT SIGN
    U+066A ٪  ARABIC PERCENT SIGN

No there aren't. Each of these has usage context that is not appropriate here. This text is neither in full-width kana, subscripts, nor arabic.

[Y_Y]

Sorry, I only use 10pc of my brain.

Speak for yourself. I have ﹪ bound to ⌘⌥⇧5!

The fact you could type that sentence doesn't mean the whole sentence "is on your keyboard"

It seems to be a bit old-fashioned and predominantly (but not exclusively) British: https://english.stackexchange.com/a/607950

Obviously Australians are somewhat more influenced by British usage than say Americans are, although not always (e.g. we say “truck” not “lorry”-although we define the word “truck” more narrowly than Americans do)

never studied mathematics to know the meanings of the symbols? (not necessarily the author, but the readers - you attract a wider potential audience)
