A thermometer is a device that measures temperature or a temperature gradient. A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer) in which some physical change occurs with temperature, and (2) some means of converting this physical change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer).

There are various principles by which different thermometers operate. They include the thermal expansion of solids or liquids with temperature, and the change in pressure of a gas on heating or cooling. Radiation-type thermometers measure the infrared energy emitted by an object, allowing measurement of temperature without contact.

Thermometers are widely used in industry to control and regulate processes, in the study of weather, in medicine, and in scientific research.

Some of the principles of the thermometer were known to Greek philosophers of two thousand years ago; by the 18th century, standardized scales had made the readings of different thermometers inter-comparable
