David Yes, the conversion to Celsius is a bugger, isn't it? Not really if you only need it to the nearest degree. Say the temperature is 72F, take 32 off (40) and divde by 2, so you have 20. Add on a tenth (2), so in Centigrade it's 22 - Actual conversion 22.22 59F 27 14 rounding up 14+1.4 15C rounding down I suspect that Derek's humour is the same as mine and that he meant conversion from Centigrade to Celsius!!
