Density is a measure of how much matter is contained in a certain volume. It is often expressed in units of mass per unit volume, such as grams per cubic centimeter.
The SI unit of density is kilograms per cubic meter (kg/m3). Other commonly used units include grams per cubic centimeter (g/cm3) and grams per milliliter (g/mL).
Density is calculated by dividing the mass of an object by its volume. The formula for density is D=m/V, where D is density, m is mass, and V is volume. This formula is commonly used in physics and chemistry.
Density and specific gravity are both measures of how compact or dense a substance is. However, density is an absolute measure, while specific gravity is a relative measure that compares the density of a substance to the density of water at a specific temperature. Specific gravity has no units, while density is expressed in units of mass per unit volume.
Using the correct units when measuring density is important because it ensures that the measurement is accurate and can be easily compared to other measurements. Using the wrong units can lead to confusion and incorrect calculations.
