Multiply that result by 1.8(=9/5) to get changes in degrees Fahrenheit. Best estimate for absolute global mean for 1951-1980 is 14C = 57.2F, (earlier we used 15C i.e. 59F) so add that to the temperature change if you want to use an absolute scale. Example -- J-D 81 : change=.39C or .70F ; absolute scale: 14.39C or 57.90F
