SPECIFIC GRAVITY HOW TOYou need to become familiar with all these terms and concepts before you can begin to understand what specific gravity is, let alone how to calculate it. In the specific gravity calculation, density is expressed with the Greek symbol ρ pronounced rho. Standard pressure is 760.000 mmHg (millimeters of Mercury). ![]() Standard Temperature is 4 degrees Celsius (39 degrees Fahrenheit). In order to calculate their density at Standard Temperature and Pressure (STP), you will need to divide the mass and the volume. The two things that you need to know before you can calculate specific gravity is the density of the solid object or liquid, and the density of the water. If, however, the specific gravity is less than one, then the object or liquid in question will float. The formula for specific gravity establishes that if the specific gravity of a solid object or a liquid is greater than one, then the object or liquid in question will sink. The name of the force that determines whether an object will sink or float on water is known as specific gravity. “Nothing is softer or more felxible than water, yet nothing can resist it.” - Lao Tzu According to this principle, what buoys up any object is the force that is equal to the weight of the water (or liquid) that has been displaced by it. This is what we now referred to as Archimedes’ Principle. He is credited with having discovered a method for determining the volume of objects that had irregular shapes. ![]() The first person to understand the importance of buoyancy was the Greek mathematician and inventor Archimedes of Syracuse (c. “Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.” - Archimedesīuoyancy is the main principle we must understand in any approximation of why some objects float while others do not. The specific gravity of water is quite a complex issue and one of the best ways to understand it is by taking stock of some of the objects that float and those who sink. Some people wonder why some objects float on water while others sink. The specific gravity of water varies with temperature, however, at 4 degrees Celsius the specific gravity of water is 1. ![]()
