Clinical thermometer is used to measure the human body temperature. A laboratory thermometer is not used for this purpose of measuring body temperature; it is generally used for the measurement of objects which generally have a temperature range outside that of a normal human body.

Heat flows across temperature differences. There are three modes of heat transfer: conduction, radiation, and convection. Conduction and radiation are fundamental physical mechanisms, while convection is really conduction as affected by fluid flow.
