Cant help it, I still think in farenheit, and end up converting it in my head before I speak. Tend to do the same with feet and inches sometimes. And sometimes a bit of both, 25ins and 7mm, long :D is not unheard of at work.
For me warm days are in farenheit and cold days are now centigrade. To bore you with science - name a temperature scale that runs from 0 to 100. Answer Farenheit. The coldest mixture that he could get was by mixing ice and salt and he defined this as 0 F and body temperature was defined as 100 F. Which has since be relegated to 98.6 F. So we do use the decimal system after all. The original decimal system also had 100 seconds to the minute and 100 minutes to the hour - not sure how many hours there were. Is this change buried in the new EU treaty? :D Question: - at what temperature does mercury freeze? Answer: at minus 38 degrees. Question: on which scale is that? Answer: it doesn't matter. That's the point at which both are the same.
Interesting Peter, I knew that minus 40 was the same in both, I did not realise that that was very close to the feezing point of mercury.
I'm okay with both now, but must admit I am more comfortable with metric now and find Imperial difficult. The two easy ones are ... 16 C is 61 F 28 C is 82 F My silly system is, if I'm 20 here, I double, ie 40 and add 30 so 70 ... more or less there .. it does change when you go very hot or very cold, though.
Yea but; a water freezing point of K 273 degrees and a boiling point of K 373 is a bit excessive. Though just like celsius and centigrade they are still just a handy 100 degrees apart, (much better than Farenheit) though the K scale is rather harder to conceptualise than the Celsius/Centigrade most of us hear on the weather forecast or read off themometers. I'm quite happy with degrees C and just can't imagine what zero degrees K (minus 273 C) must be like. Rather very chilly I guess :D
16 - Very comfortable 20 - Shorts & teeshirt 25 - A greek taverna on an August/September evening 30 - Where's the shade?
And don't forget the Reaumur scale. In France water used to boil at 80 degrees Reaumur, before the adoption of centigrade. I believe the Reaumur scale was still being used in Russia well into the 20th century.
Zero K is Absolute zero - the temperature at which electrons stop orbitting. It cannot be attained. </font>[/quote]Yes, but the closer you get to absolute zero the lower resistance becomes (copper has zero resistance at at minus K 234) and the faster electrons flow. Which is one reason as to why super-cooling is being is being explored as one way of increasing computer processing speed. Now this may explain why my PC in chilly Scotland runs faster than Lady of Leisure's in Portugal :D :D
Whatever happened to body temperature being 98.4 instead of 98.6? :confused: Maybe people are more hot blooded nowadays :D Does it change if you are feeling one degree under?
