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

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 = weight / volume. Where: The SI unit of specific weight is Newton per cubic meter (N/m 3). The US customary unit of specific weight is pounds-force per cubic foot (lbf/ft 3). The …

Specific weight is defined as the ratio between weight and volume. Specific weight can also be defined as the product between density and gravitational acceleration.

Specific weight represents a material’s weight per unit of its volume. It quantifies the force exerted by gravity on a given substance within a defined space. Specific weight is calculated by …

Learn about specific weight and its relationship with density. Understand the formula for calculating specific weight and its applications in various scientific fields.

Dec 25, 2024 · Definition and Formula The specific weight of a substance is defined as the weight of the substance per unit volume. Mathematically, it is represented as: γ = ρg

Nov 10, 2025 · Specific weight is defined as the weight exerted by a substance per unit of its volume, often represented by the Greek letter gamma (gamma). This relationship is expressed …

Nov 11, 2025 · It is denoted by the symbol w (sometimes γ) and is measured in newtons per cubic meter (N/m³). The formula for specific weight is: where ρ = density of the fluid (kg/m³), and g = …

Specific weight (γ) calculator with unit conversion. Compute γ = ρ·g or density from specific weight. Supports N/m³, lb/ft³, kg/m³, lbm/ft³, slugs/ft³.
