The difference between density, specific weight, and specific gravity. Including formulas, definitions, and reference values for common substances.

Density (volumetric mass density or specific mass) is the ratio of a substance's mass to its volume. The symbol most often used for density is ρ (the lower case Greek letter rho), …

This density to weight calculator gives you a quick way to go from the density of an object made from a known substance to its weight, as long as you know its volume.

The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.

Density is mass/volume. The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight …

Dec 10, 2025 · Density, mass per unit volume of a substance. The formula for density is d=M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of …

This lesson explains density as the physical property in chemistry that quantifies how mass is concentrated in a given volume. Gain a comfort using the formula D = m/V and explore how …

Mass density is the mass of an object per unit volume, measured in kilograms per cubic meter, while weight density is the weight of an object per unit volume, measured in newtons per cubic …

Dec 21, 2020 · In general, a density is usually a quantity such as mass, divided by an area or volume. A weight density would therefore describe how the weight of some object is …

Dec 6, 2025 · The direct answer to whether density affects weight is that it does not; weight is a direct function of mass, not density. The scientific formula for weight confirms this relationship, …
