One rarely sees the extreme ends of the prefix table used.
In an article, "Davy Jones's heat locker", in the August 23-29 2014 issue of The Economist (pp. 73/74), the author uses the phrase "69 zettajoules of heat (that is, 69 x 10^21 joules - a huge amount of energy)". I think that the use of the spelled out zettajoules nicely emphasizes the extreme size of the value being discussed since the prefix zetta is rarely seen in print.
All values in the article are given in SI units. Nice. Very, very nice! Jim -- James R. Frysinger 632 Stoney Point Mountain Road Doyle TN 38559-3030 (C) 931.212.0267 (H) 931.657.3107 (F) 931.657.3108
