> Of Pat Naughtin >I have heard that the USA Weather Service changed to degrees Celsius in 1995
At 0800Z on 1 July 1996, the FAA started using Celsius. The National Weather Service and the Department of Defense acted in parallel. The formal scope of the change was limited to aviation weather. http://www.asy.faa.gov/safety_products/NewformatsBrochure.htm http://metar.noaa.gov/table_master.jsp?sub_menu=no&show=text_overview.jsp&ti tle=title_program_overview
