A density calculator is a tool that calculates the density of a substance based on its mass and volume. The density of a substance is the measure of how much mass is contained within a given volume. It is usually expressed in units of grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³), although other units such as pounds per cubic inch (lb/in³) or ounces per gallon (oz/gal) may also be used depending on the context.
To use a density calculator, you need to input the mass and volume of the substance you are interested in, and the calculator will calculate the density for you. This can be useful in a variety of fields, such as chemistry, physics, engineering, and materials science, where knowing the density of a substance is important for understanding its properties and behavior.
