Divide by 100 to get changes in degrees Celsius (deg-C).
Multiply that result by 1.8(=9/5) to get changes in degrees Fahrenheit (deg-F).

Best estimate for absolute global mean for 1951-1980 is  14.0 deg-C or 57.2 deg-F,
so add that to the temperature change if you want to use an absolute scale
(this note applies to global annual means only, J-D and D-N !)

Example      --      Table Value :      40
                          change :    0.40 deg-C  or  0.72 deg-F
