In mathematics

Ninety-four is the twenty-ninth distinct semiprime and the fourteenth of the form (2.q). The aliquot sum of 94 is 50 within the aliquot sequence (94,50,43,1,0) 94 being the ninth composite number in the 43-aliquot tree. 94 is the second number in the third triplet of three consecutive distinct semiprimes, 93, 94 and 95.

94 is a 17-gonal number and a nontotient.

Since it is possible to find sequences of 94 consecutive integers such that each inner member shares a factor with either the first or the last member, 94 is an Erdős–Woods number.

In decimal, 94 is a Smith number.

In computing

The ASCII character set (and, more generally, ISO 646) contains exactly 94 graphic non-whitespace characters, which form a contiguous range of code points. These codes (0x21–0x7E, as corresponding high bit set bytes 0xA1–0xFE) also used in various multi-byte encoding schemes for languages of East Asia, such as ISO 2022, EUC and GB 2312. For this reason, code pages of 94² and even 94³ code points were common in East Asia in 1980s–1990s.
