Your pocket calculator must be pretty advanced to support hexadezimal arithmetic. Of course those things do exist, but they are definitely *NOT* commonplace. At least I've never seen keys 'A' to 'F' on e.g. the typical TI-30. jue

Back in the early 80's IIRC Texas brought out the first hexadecimal calculator (also did decimal, octal and binary). Common in programming dept's. Casio started producing multiple base calculators in the late 80's and most of their scientific ones support it. These days even my calculator from the pound shop has it and the answer to the above is 21E42E = 2221102 > > jue

Also the angle of the thread may be 60 degrees instead of 55, so it will turn in for a while and then get stuck - unless of course SAE cribbed it. Whitworth heads were quite large and were reduced during the war to save metal. > >> >> Touch�! >> >> Even though the Yanks left the Empire they still won't join the rest of >> the world. > > And go metric, you mean?

Item 1 Mars Climate Orbiter crashes and burns* $327,600,000.00c So that's about one dollar per citizen - bad start! (OK so in the fifties the Brits made a car engine that had metric bolts with imperial heads... ) > Hexadecimal really makes far more sense than metric, and that is closer to > the old familiar English systems of measure.

As for the pound sterling this is the last currency in the world that has any relation to the original pound weight of silver that the Libra (�) in Lsd stood for in Roman times. By 1914 there were four ounces (~112g) of 92.5% silver to the �, but now one pound will only buy you about 4 to 5g. Gordon Brown and Alistair Darling are working hard to reduce this as rapidly as possible :-((. The French Livre blew up during their revolution with a loaf of bread costing �15 or more and was replaced by the Franc (revalued by 100 ~1960). By the time the Italian Lira was replaced by the Euro there were thousands to the Euro. * http://www.google.co.uk/url?q=http://en.wikipedia.org/wiki/Mars_Climate_Orbiter%23The_metric.2Fimperial_mix-up&usg=AFQjCNHBbstCpB4S2gxZe2bJ9jJJGEClxw&ei=ng37SpzEINeMjAfr0bGxBA&sa=X&oi=section_link&resnum=2&ct=legacy&ved=0CAoQygQ |
