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.


Degree Réaumur is a temperature scale for which the freezing and boiling points of water are defined as 0 and 80 degrees respectively. The Réaumur scale was used widely in Europe, particularly in France, Germany and Russia.


Degree 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).
