Centigrade clearly doesn't to weather forecasters, several of whom have 
recently said that temperatures of 11 degC are twice the seasonal 
average - since "twice" implies an absolute rather than relative scale, 
they must mean that temperatures would normally be 142K (or minus 131 
degrees Centigrade).
(Sorry for the pedantry - just been listening to "More or Less", and 
their more rigorous approach is hard to shake off!)
