It is expressed in units of pounds per cubic foot (lb\/ft3) or kilograms per cubic meter (kg\/m3). The unit weight of soil is affected by the following factors:<\/p>\n<ul>\n<li>The void ratio of the soil: The void ratio is the ratio of the volume of voids to the volume of solids in the soil. A higher void ratio means that there is more space between the soil particles, and the soil will have a lower unit weight.<\/li>\n<li>The water content of the soil: The water content of the soil is the ratio of the weight of water to the weight of solids in the soil. A higher water content means that the soil particles are surrounded by more water, and the soil will have a lower unit weight.<\/li>\n<li>The effective stress on the soil: The effective stress on the soil is the difference between the total stress on the soil and the pore water pressure. A higher effective stress means that the soil particles are more tightly packed together, and the soil will have a higher unit weight.<\/li>\n<\/ul>\n<p>When soil is submerged in water, the water pressure in the pores of the soil increases.
