Not quite right. Us English (and the Scots and Welsh) still use the imperial system for the important parts. Beer still comes in pints, we drive at miles per hour, our doors are six foot six high and so forth. Even when we are forced by Europe to use metric units, we mix things -- for example I recently bought stuff for a building project which included a two metre length of 2 by 1 wood (where the cross section is still measure in inches) and a one metre section of 2 inch (diameter) plastic piping. It is true that we've been forced to weight foods in metric but that has led to weird things like it being (technically) illegal for your butcher to offer sausages at a price for a pack of six -- he has to offer them at so much per kilogram!! The petrol stations are forced to sell us petrol and diesel by the litre not the gallon -- but that was a government trick to avoid us noticing that the price had gone up fivefold. Funnily enough most gas tanks still hold 10 gallons not a round number of litres. The good news is that it is still illegal (in England anyway) for road signs to be installed that are in metric units and not including their imperial equivalent. Bridge heights are still in feet and inches and even if some Europe loving authority decided to use the French system, they have to put the imperial distance too -- or suffer quite a large fine. As someone else mentioned, I've used metric units for scientific work for most of my life, but I still think of temperature in Fahrenheit, distance in miles, fuel consumption in miles per gallon, meat in pounds and beer in pints -- the latter most often!! - -- Regards Andy, G8TQH http://www.rickham.net/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) iD8DBQFCrTdmGhQb5Xlw1yURAuP3AJ9LtoAgpImmCbyNAsJEMnEyFXqIRwCeNs3w hzUB9zTWu/uDhMjR1LOrUdg= =5akb -----END PGP SIGNATURE----- _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Personally, I use one of these...
http://www5b.biglobe.ne.jp/~tomozawa/sr-annex/cat/hemmi/hemmi- 266/hemmi-266e.htm It has all the scales for all the frequency, wavelength calculations plus XL, XC, CF,CZ, Fc, Zo, L,C,Z,etc...scales... At 10 inches (not 254mm!!) it gives results close enough for practical work... I love mine :-)) Dave KK7SS > http://www5b.biglobe.ne.jp/~tomozawa/sr-annex/cat/pickett/pick > ett-n16es/ pickett-n16ese.htm > > for all your radio work! :-) _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
