With petrol being so expensive 'rounding' is not very helpful. A penny a litre on a full tank is 50p which is a very useful thing to remember, as it gives you a feel for what you are buying, something I could never get with litres before. Now I can compare prices at the pumps because 78.6 and 79.4 mean nothing to me.
Actually,its illegal to sell draught beer in litres. You're allowed to (but not obliged to) sell milk and orange juice in pints too if they're delivered to the door, but draught beer *has* to be sold in imperial measures. Brian
I do know you are boring. You are rapidly causing me to lose the will to live in usenet form, christ knows what effect you'd have IRL.
Not any imperial measure. IIRC draught beer has to be sold in quantities of 1/3 pint or multiples of 1/2 pint.
Only SI prefixes are base related. The major benefits of SI (e.g. only one unit for each quantity) are independent of base. If you want to use a different base, then avoid the prefixes or use a different set. See: http://www.iec.ch/online_news/etech/arch_2003/etech_0503/focus.htm A base 12 system uses powers of 12 only (12, 144, 1728 etc). The old system has no base, just a series of unrelated conversion factors e.g. 12, 3, 22, 10, 8.
.... That is the result of falling standards in education. I never had problems working out what ten bob would buy me at 1/8d a gallon. Colin Bignell
Well if you can do 78.4 * 49 in your head you probably went to a better school than I did.. I left University with a degree in Electronics before standards started falling.
Took me a few minutes to think about it in real money, but I got there in the end. No, I won't spoil the fun and tell everyone.
than you need, your only problem is spending it, However some people do How can it be easier to budget in gallons when petrol is sold in litres?
