Celsius to Fahrenheit, Why ?

Well, not the most important topic of our world. Nevertheless I find it mildly irritating that many UK weather forecasters or radio announcers very often convert Celsius to Fahrenheit. As I recall, the BBC began to convert temperatures on their nightly weather map as far back as 1964. The aim being to phase out Fahrenheit. Yet now in 2011 we are still being told what a temperature is in both scales. Even on a recent plane journey I made, the pilot of a British airline when announcing weather conditions in the UK, converted Celsius to Fahrenheit. This was on a european flight between two countries which both use Celsius. One of them being Britain I admit, but how long does it take to just forget Fahrenheit.? As far as I am aware the United States and Belize are the only countries that use it. The other point is that in the UK, if is is hot,  then the media refer to temperatures in Fahrenheit. Well it seems hotter doesn't it ?100 degrees sounds much more than 38 degrees. However below freezing is spoken in Celsius. Just sort it out please. Stop living in the past and confusing the issue by using two scales when hot or cold !
