Soil Unit Weight on the Geotechnical Information Website
Unit weight of a soil mass is the ratio of the total weight of soil to the total volume of soil. Unit Weight, g, is usually determined in the laboratory by measuring the weight and volume of a relatively undisturbed soil sample obtained from a brass ring.Measuring unit weight of soil in the field may consist of a sand cone test, rubber balloon or nuclear densiometer.
