A load measurement sub for measuring a load transferred between the sub and an inner surface of a tubing string includes a housing. The housing includes a central axis, an internal cavity, and a radially outermost surface. In addition, the load measurement sub includes a first load measurement assembly at least partially disposed within a first port extending from the radially outermost surface to the internal cavity. The first load measurement assembly includes a first button extending radially from the first port and the radially outermost surface of the housing. The first load measurement assembly also includes a first load cell. Further, the load measurement sub includes a first biasing member disposed between the first button and the first load cell. The first biasing member is configured to bias the first button away from the first load cell.
