A mobile terminal which makes it possible to automatically calculate a step length of a user with accuracy. A step count-acquiring section acquires a step count of the user of a mobile terminal. A position calculating section calculates a position of the mobile terminal. A center position-calculating section calculates a center position of a plurality of positions calculated by the position calculating section. A covered distance-calculating section calculates a distance covered by the mobile terminal based on a plurality of the center positions calculated by the center position-calculating section. A step length-calculating section calculates the step length based on the step count acquired by the step count-acquiring section and the covered distance calculated by the covered distance-calculating section.
