A work machine is provided that includes: an attachment attached on an upper rotating body and including at least a boom, an arm attached on an end of the boom, and an end attachment attached on an end of the arm; and a control device, wherein the control device compensates for a torque, which causes the boom to rotate, based on either or both of a centrifugal force on the arm and an inertial force on the arm, and calculates a weight of a conveyance object conveyed by the attachment based on the torque for which the compensation is performed.
