  • How to Calculate Unit Weight Sciencing

    Unit weight is one of a number of related basic physics terms that leads some students to confusion. Also called specific weight, unit weight is in a family of terms that, loosely speaking, define and relate size (volume), amount (mass), concentration (density) and force (weight), along with specific gravity.

    penetrometer reading is higher, the unit weight should be increased from the average, and if the pocket penetrometer reading is lower, the unit weight should be decreased from the average. In the absence of SPT data, unit weights can be estimated using Charts 3 and 4 and the strength data (e.g., pocket penetrometer reading).
