Saturated Unit Weight - rea-llc.com

For an SM material with a dry unit weight of 100 pcf, the void ratio would be roughly 0.68 with a saturated unit weight of 124 pcf, considerably less than a well grade sand (SW). For the purpose of the software, we will default to a moist unit weight of 120 pcf and a void ratio of 0.4 for a saturated unit weight of 135 pcf.

Specific weight - Wikipedia

The specific weight (also known as the unit weight) is the weight per unit volume of a material. The symbol of specific weight is γ (the Greek letter Gamma). A commonly used value is the specific weight of water on Earth at 4°C, which is 9.807 kN/m 3 or 62.43 lbf/ft 3.
