“Ugh. An Australian should use⟳ Australian numbers (the same as British), not American. 10^27 is 1,000 quadrillion (or a quadrilliard). An octillion would be 10^48.”

“Your estimation was quite accurate. In a body of 75 kg of water, there are roughly 2.5 x 10^28. That's 25 octillion (US) or 25 quadrilliard (EU).”

“There are weak keys in the sense⟳ that their use⟳ by foisting chosen plaintexts can be proved, which could be interesting for chip cards with a ‘burnt-in key’. First of all, however, these keys can be easily avoided—one only needs to XOR all subkeys with the hexadecimal number⟳ 0x0dae—and second, the probability that such a key can be caught is 2⁻⁹⁶; that is about one out of 10²⁹ randomly selected keys (this number⟳ even has a name⟳: 100 quadrilliards).”

“In the European system, 10⁹ is a milliard, 10¹² is a billion, 10¹⁵ is a billiard, 10¹⁸ is a trillion, 10²¹ is a trilliard, 10²⁴ is a quadrillion, and 10²⁷ is a quadrilliard. To avoid⟳ confusion in expressing these numbers, the SI prefixes are preferred.”
