1. A work machine comprising:
a work implement including a bucket, a boom that raises and lowers the bucket, and a work tool cylinder that drives at least one of the bucket and the boom;
a work phase sensor that senses information about a work phase including excavation;
a cylinder pressure sensor that senses cylinder pressure of the work tool cylinder; and
a controller that distinguishes the work phase by the work implement based on the information sensed by the work phase sensor, and switches correction of the cylinder pressure sensed by the cylinder pressure sensor when distinction of excavation in the work phase switches.
