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
abs. scale if global annual mean : 14.40 deg-C or 57.92 deg-F

NASA usually up-dates “dTs” in the middle of each calendar month. NASA does not maintain a publicly accessible archive of “dTs”. Only the latest edition of “dTs” is available at NASA's website for the public to inspect. NASA also publishes “The global land-ocean temperature index”.
