Unit Weight of soil. Geotechnical Engineering. The ratio of the weight of a material to its volume is its unit weight, sometimes termed specific weight or. weight density. The unit weight of water, Yw, is 9.81 kN/m3 in the SI system and 62.4 lb/ft3 in the English. system. The unit weight of solids, Y s, varies with the mineralogy of the soil particles but is commonly in. the range of 26.0 to 27.0 kN/m3 or 165 to 172 lb/ft3. The total unit weight of a soil (the solids-water-air.
