Specific Weight is defined as weight per unit volume . Weight is a force . The SI unit for specific weight is [N/m 3]. The imperial unit is [lb/ft 3]. Specific Weight (or force per unit volume) can be expressed as. γ = ρ a g (4) where γ = specific weight (N/m 3], [lb/ft 3] ρ = density [kg/m 3], [slugs/ft 3]

The specific weight of a substance is the weight per unit volume. Specific weight is usually given the symbol \(\gamma\) ("gamma") and can be calculated as the product of density times the local acceleration of gravity: \[\gamma=\rho g \nonumber \] Any values of specific weight you find listed in a table have, of necessity, assumed a value for ...

The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: Its unit of measurement in the International System of Units (SI) is...
Liquids and gases are considered to be fluids because they yield to shearing forces, whereas solids resist them. Like solids, the molecules in a liquid are bonded to neighboring molecules, but possess many fewer of these bonds.
Specific weight has units of weight per unit volume, so its value depends on acceleration under gravity or “g.” The units of specific weight are N/m (i.e., N m ) in the SI system or lb/ft (i.e., lb ft ) the USC system.
Key Equations. Summary. 14.1 Fluids, Density, and Pressure. A fluid is a state of matter that yields to sideways or shearing forces. Liquids and gases are both fluids. Fluid statics is the physics of stationary fluids. Density is the mass per unit volume of a substance or object, defined as ρ = m V ρ = m V. The SI unit of density is kg/m 3.
