What is temperature?Temperature is a measure of hotness or coldness of a physical object with reference to some standard value. Similar to pressure or density, it is an intensive property. Meaning that it does not change as the amount of matter changes.
InputDegree Rankine is similar to the Kelvin scale in that it starts at absolute zero and 0°R is the same as 0K (Kelvin) but is different as a change of 1°R is the same as a change of 1°F and not 1°C (Celsius).
Kelvin is the base unit of temperature in the International System of Units (SI). Its 0 value is the absolute zero of the thermodynamic temperature scale, a state at which the fundamental particles of nature have minimum vibrational motion.
