"Soil Specific Gravity" is an Android app designed to help users calculate the specific gravity of soil effortlessly. Utilizing the formula Gs=[Ws/(Ws+W2-W1)]×Gw, where Ws is the weight of dry soil, W1 and W2 are weights involving a pycnometer, and Gw is the water specific weight at a given temperature, this app provides a straightforward method for soil analysis essential in geotechnical engineering and environmental studies.
