Many people like using pi tapes to measure the pipe size. Pi tapes, which wrap around the pipe the same way but have units in diameter, can be expensive. With calculators everywhere today, dividing by 3.14 is a snap, making these pi tapes not even necessary.
Fuck is an obscene English-language word, which refers to the act of sexual intercourse and is also commonly used as an intensifier or to denote disdain. Its origin is obscure but is usually considered to be first attested to around 1475, although it may be considerably older.
Fuck isn't an Anglo-Saxon word either. Some of today's swearwords did indeed originate in Old English, including shit, arse, turd, and the British bollocks. The f-word is of Germanic origin, related to Dutch, German, and Swedish words for to strike and to move back and forth.. It first appears, though, only in the 16th century, in a manuscript of the Latin orator Cicero.
