ABSOLUTE TEMPERATUREThe fundamental temperature scale with its zero at absolute zero and expressed in degrees Kelvin. One degree Kelvin is equal to one degree Celsius or one degree Centigrade. For the purpose of practical calculations in order to convert Celsius to Kelvin add 273. It is normal for the degree Kelvin to be abbreviated in mathematical formulae to ‘K’ with the degree symbol being omitted. 
CELSIUSA temperature scale with gradients between the freezing and boiling points of water are divided into 100 equal parts. 
THERMOGRAPHYThe use of infrared thermography whereby temperatures of a wide variety of targets can be measured remotely and without contact. This is accomplished by measuring the infrared energy radiating from the surface of the target and converting this measurement to an equivalent surface temperature. 
CONVERSION SCALEA scale for the conversion of units of one measurement to equivalent units of another measurement.
