Absolute temperature

Absolute temperature, also called thermodynamic temperature, is the temperature of an object on a scale where zero is taken as absolute zero. Absolute temperature scales are Kelvin and Rankine.

Absolute zero is the temperature at which a system is in the state of lowest possible (minimum) energy. As molecules approach this temperature, their movements continue to slow down. The kinetic energy of the molecules becomes negligible. However, the molecules will never stop moving nor have no energy.  

It is the lowest temperature a gas thermometer can measure. No electronic devices work at this temperature. No living thing can survive in this temperature.

Examples
Common temperatures in the absolute scale are:
0 °C (freezing point of water) = 273.15 K
25 °C (room temperature) = 298.15 K
100 °C (boiling point of water) = 373.15 K
0 K (absolute zero) = -273.15 °C
233.15 K (equal measures in Celsius and Fahrenheit)= -40 Celsius
 Triple point of water= 273.16K (equal measure in Celsius) 0.01°C.

Conversion
To convert from the Celsius scale into the absolute temperature, you add 273.15 and change °C to K. To get a temperature on the absolute scale to the Celsius scale, subtract 273.15 and change K to °C.
This is normally used in the science world. Kelvin is used globally as a part of the International System of Units. It is one of the 7 base units of the system.
The value of absolute temperature is 0 K.

 Celsius to Kelvin: K = C + 273.15
 Kelvin to Celsius: C = K - 273.15
 Fahrenheit to Rankine: R = F + 459.67
 Rankine to Fahrenheit: F = R - 459.67
