Sorry - just a little pet hate of mine! I think I was King Canute in > another life because I doubt I'll stem the tide of "kill OM ittah" ;-) I agree with you on the kil OM ittah thing - it really annoys me as well. After all we don't go around kil OG rums or kil OB ites. The wikipedia article on LH/RH driving is interesting. Seems driving on the left was much more common in the past. Napoleon and American teamsters are the main cause of driving on the right. http://en.wikipedia.org/wiki/Right-_and_left-hand_traffic

My doctors always measure weight in Kg, makes it easy to work out BMI. As I'm about 5ft 8inches this equals 1.72 Metres. 1.72 squared is near as dammit 3 so I just divide my weight in Kg by 3 to get my BMI > I prefer half a litre of my beer.

Down solely to the Irish taking a while to convert completely - and, quite probably, a lot of UK-market cars being exported used. > The situation may well have changed now with speed limit signs in km/hr > and new cars fitted with km and km/hr speedos despite being RHD. > Presumably the market for this combination is comparatively small > compared with the UK, but also includes Australia, New Zealand, Malta > and maybe Japan and India (do they measure speed in km/hr?). I suspect there's as many RHD km/h cars sold as RHD mph ones. Yes, Japan and India use km.

By "beer", are you referring to bland, dead fizz?

I'm one of those half-and-half people who is old enough to have been brought up with imperial units so I estimate distances in inches, yards etc and know my height and weight in feet/inches and stones/pounds, BUT if I'm asked to measure anything I always do it in metric units for ease of calculation and for consistency between linear, volumetric and weight units. A box that it 10 cm cubed contains a litre and weighs 1 kg if it's filled with water. There is no such simple relationship for imperial: there is not an integer relationship between cubic inches and gallons: - one imperial (UK) gallon is 277.42 cubic inches - one US gallon is defined to be 231 cubic inches Neither of these is a nice round number. I first realised that there was no simple relationship between linear and volumetric units when I had to work out how heavy a copper hot water cylinder would be to see if the joists that it was standing on would take the weight, and I only had a tape measure with inches on it. Not knowing the conversion factor (277.4 is not a very memorable number!), even if I did know that a gallon of water weighs 10 lb, I had to convert the height and circumference to metric units (1 inch is about 2.5 cm, pi is approximately 22/7) and perform the calculations by hand on a piece of paper (I didn't have a calculator either at the cottage where I was helping my dad fit the cylinder). For the record, I've just measured my own hot water cylinder and it's 120 cm high by 122 cm circumference, so its radius is 122/(2*pi) = 19.4 cm and hence its volume is 120 * pi * (19.4)^2 = (approx) 142,000 cm^3 or 142 litres. So the weight of the cylinder will be 142 kg plus the weight of the copper itself. We estimated the total weight would be around 150 kg so if the joists took the combined weight of dad and me standing on it, it would take the weight of the tank. We were lighter in those days - today we'd add up to about 220 kg, but such is life! |
