TEMPERATURE AND
ITS MEASUREMENT
Temperature (which measures average kinetic energy of the molecules) can be
measured using three common scales: Celsius. Kelvin and Fahrenheit. We use the
following formulas to convert from one scale to another. Celsius is the scale most
desirable for laboratory work. Kelvin represents the absolute scale. Fahrenheit is the old
English scale which is never used in lob.
