(physics) The temperature at which hadronic matter (i.e. ordinary matter) is no longer stable, and must either "evaporate" or convert into quark matter.

(physics) The fundamental upper limit of temperature conceivable under current models of physics, in which all matter is accelerated as quickly as possible to the speed of light, approximately 1.41679 × 10³² kelvins.

The apparent temperature of the environment; may be different from the actual temperature because of factors such as wind chill or humidity

(sciences) A coefficient which relates the change of the magnitude of a physical property to a unit change in temperature.

The temperature at which a bitumen attains the proper viscosity for built-up membrane application.

The lowest temperature at which combustion will occur spontaneously under specific conditions.

(physics) The temperature at the critical point of a substance, i.e. the temperature above which the substance cannot be liquefied.

The temperature that a dry parcel of air would need in order to have the same density as a parcel of a specific temperature and humidity.

The temperature a parcel of air would have if brought adiabatically to a standard reference pressure
