Dennis Brownridge in USMA 9639 disapproved of utility billing by the kilowatt-hour. >This is bad news. Instead of modernizing to SI, they have simply switched >from one antiquated non-SI unit to another. In general I favor SI units. However, I think the kilowatt-hour is more meaningful to the consumer than the kilojoule or the megajoule simply because one can more easily recall the duration of most activities in hours rather than seconds. It is tedious to divide kilojoules by 3600 to get kilowatt-hours.
