Temperature measurement calibration

Thermodynamicmarine fuel dispensers(symbol T) is the physical fundamentals hand, its unit Kelvin (Kelvin symbol K), defined as the thermodynamic temperature of the triple point of water 1 / 273.16. As the previous definition of the temperature scale used with 273.15K (freezing) to represent the difference between the petrol dispenser pump, so it retains all methods. By definition, equal to the size of degrees Kelvin, the temperature difference can also be expressed in degrees Celsius or Kelvin to represent. International Temperature Scale ITS-90 also defines international Kelvin (symbol T90) and the International Celsius (symbol t90)
