In fluid mechanics, specific weight represents the force exerted by gravity on a unit volume of a fluid. For this reason, units are expressed as force per unit volume (e.g., N/m 3 or lbf/ft 3 ). Specific weight can be used as a characteristic property of a fluid.
Online calculator, figures and table showing density and specific weight of pentane, C5H12, at temperatures ranging from -130 to 325 °C (-200 to 620 °F) at atmospheric and higher pressure - Imperial and SI Units.
Specific weight, also known as unit weight, is a physical quantity that represents the weight per unit volume of a substance or material. It is defined as the weight of a substance divided by its volume and is typically expressed in units of force per unit volume, such as Newtons per cubic meter (N/m 3) or pounds-force per cubic foot (lbf/ft 3).
The symbol used for specific weight is the Greek letter γ (gamma). The SI unit of measurement for specific weight is [N/m 3]. The unit of measurement for specific weight can easily be demonstrated from equation (3). The unit of measurement for density is [kg/m 3].
The specific weight of a substance is the weight per unit volume. Specific weight is usually given the symbol γ ("gamma") and can be calculated as the product of density times the local acceleration of gravity: γ = ρg Any values of specific weight you find listed in a table have, of necessity, assumed a value for the local acceleration of ...

Specific weight can be calculated using the formula: $$ ext {Specific Weight} = ext {Density} imes g$$, where $$g$$ is the acceleration due to gravity. Fluids with higher specific weight exert more pressure at a given depth compared to those with lower specific weight, affecting hydrostatic forces on submerged surfaces.
The specific weight of a material is calculated from the density of the material using the following equation: where γ is the specific weight, ρ is the density of the material, and g is gravitational acceleration. Therefore, it can be seen that the specific weight is the density of a material times gravity.
Specific weight (unit weight), ", is the weight of fluid per unit volume. The use of specific weight is most often encountered in civil engineering projects in the United States, where it is commonly called “density.”. The usual units of specific weight are lbf/ft 3.
