What does temperature measure?
Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy present in all matter which is the source of the occurrence of heat a flow of energy when a body is in contact with another that is colder or hotter. Temperature is measured with a thermometer.

Degree - Wikipedia
Many methods have been developed for measuring temperature. Most of these rely on measuring some physical property of a working material that varies with temperature. One of the most common devices for measuring temperature is the glass thermometer. This consists of a glass tube filled with mercuryor some other liquid which acts as the working fluid. Temperature increase causes the fluid to expand so the temperature can be determined by measuring the volume of the fluid. Such thermometers are usually c…
Historically there are several scientific approaches to the explanation of temperature: the classical thermodynamic description based on macroscopic empirical variables that can be measured in a laboratory; the kinetic theory of gases which relates the macroscopic description to the probability distribution of the energy of motion of gas particles; and a microscopic explanation based on statistical physics and quantum mechanics . In addition rigorous and purely mathematical treatments have provided an axiomatic approach to classical thermodynamics and temperature. Statistical physics provid…
