The specific gravity equation is: Since the specific gravity formula consists of one density divided by another, the specific gravity units don't exist. When you weigh an object, it returns a number in pounds or kilograms, which represent weight units. Substances marked with an asterisk (*) are not at STP. Let us take the any material density and density of water. And that's why 92% of If the chamber's volume is held constant while some molecules are removed, the density decreases and the specific volume increases. Can an object with a specific gravity of 1 vary in how deep it is submerged or will it always just float directly beneath the surface of the fluid? The equation may be used when dealing with gases, but the density of the gas (and its specific volume) may change dramatically with a slight increase or decrease in temperature. Common units for density include g/mL, g/cm3, g/L, kg/L, and even kg/m3.
