I don't think that the "Big Three" would quite suffice. I think we need to include degrees Celsius and watts and maybe (although a bit less important) kilopascals and kilojoules. Various combinations like kilometres per hour need to be included, also (and perhaps Wyeth meant to include them). These are all used in common everyday situations. (The lengthy list of examples is relegated to a footnote below.*) Regards, Bill Hooper ===================== *Examples: Degrees Celsius are used, not only for air temperature but also for body temperature and cooking temperature. Watts are used to measure rate the power of light bulbs and other household appliances while kilowatts are used to rate the power of motors, including automobile engines. Kilopascals can be used to measure blood pressure and tire pressure as well as atmospheric pressure in weather reports. Kilojoules will replace calories in deitetics. Heating and cooling systems will increasingly be measured in kilojoules per hour. (And the watt can be explained as nothing more than a joule per second.) Commonly encountered combinations include the following among others: speeds are measured in kilometres per hour, fuel economy can be measured in kilometres per litre (or its reciprocal in litres per megametre), health reports (such as from blood samples) give the contents of things like cholesterol and sugar in grams per litre and variations thereof, etc., etc. ============ Keep It Simple!
