      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).
