Good morning, Dai;
Yes, that is a curious way to show the temperature, but that is how the English chose to do it a few hundred years back. And, if we look critically at how I wrote it, it is not really correct. One of the problems with our system on APUG is that it does not easily recognize some of the shorthand notations commonly used. The commonly recognized symbol for "degrees" in temperature is a small circle placed up at about the level of the top of the letter "t" and then followed by the letter "C." for Celcius or Centigrade, or the letter "F." for Fahrenheit as used in the English system. Oddly enough, if we go to the temperature in Kelvins (the temperature referenced up from absolute zero, but using the "Degree C." as the temperature units), normally it is just listed as the letter "K." without the "degrees" symbol. In "Degrees C." the Absolute Zero temperature reference point is -273 Degrees C., but it is 0 K.
So, 27 Degrees F. is about -3 Degrees C.; 25 Degrees F. is about -4 Degrees C.; and 24 Degrees F. is just a little bit lower than that (about 1/2 Degree C.). Or, if you might prefer, 27 Degrees F. is about 270 K.
So, for us it was a cool day in November, but not quite truly representative of something really cold, yet.
The point that Murray mentioned originally about you having visited him is really impressive. Meeting and talking directly with people we have met on APUG and with whom we share many common interests really is fun.
