A mechanism for indicating ambient temperature of an enclosure from temperatures determined within the enclosure. The temperatures may be obtained from two or more sensors at each of two or more locations within the enclosure. The enclosure may include an apparatus inside such as electronics of which power consumption may be determined. Data including temperatures of two locations within the enclosure at various electronics power consumption levels may be entered into a 2-D plot. An approximation of the 2-D plot may be effected with an appropriate equation to be solved for ambient temperature. The data of the 2-D plot plus temperatures of a third location and air flow levels in the enclosure may be entered into a 3-D plot. An approximation of the 3-D plot may be effected with an appropriate equation to be solved for ambient temperature.
