Abstract
Devices, methods, and program products for determining an atmospheric pressure are disclosed. One electronic device includes a fan that dissipates heat. The fan rotates at a rotation speed. The electronic device also includes a heat source. The electronic device includes a calculation unit that determines an atmospheric pressure at a location of the electronic device. The electronic device also includes a first temperature sensor that senses an ambient temperature and sends first information corresponding to the ambient temperature to the calculation unit. The electronic device includes a second temperature sensor that senses a temperature of the heat source and sends second information corresponding to the temperature of the heat source to the calculation unit. The calculation unit determines the atmospheric pressure based on the first information, the second information, and the rotation speed of the fan.
