Provided discloses an electronic device for calculating physical energy consumption including a gravity sensing module, a storage module, a processing module, and a touch control display module. The gravity sensing module detects at least one movement of the electronic device for calculating physical energy consumption to generate at least one movement signal. The storage module stores a plural physical training mode and a plural predetermined exercise value. The processing module connects to the gravity sensing module and the storage module, the processing module receives at least one movement signal and generates at least one active value depending on the movement signal, and subtracts at least one active value from the predetermined exercise value corresponding to one of the physical training modes to generate at least one exercising consumption signal. The touch control display module connects to the processing module, and receives and displays at least one exercising consumption signal.
