What Is Unit Weight?

The ratio of the weight of a material to its volume is its unit weight, sometimes termed specific weight or weight density.

The unit weight of water, γw, is 9.81 kN/m3 in the SI system and 62.4 lb/ft3 in the English system.

What Is Density?

The term density is used herein to denote the mass-to-volume ratio of the material. However, some references, particularly older ones, use the term to describe unit weight.

Density is denoted by p. Because m = W/g, the unit weight terms defined above can be converted to mass densities as follows:

ρ = M/V

ρ = Density

M = Mass

V = Volume

In the SI system mass densities are commonly expressed in Mg/m3, kg/m3, or g/ml. The mass density of water can therefore be expressed ρw = 1000 kg/m3 = 1 Mg/m3 = 1 g/ml.

The mass density of soil solids typically ranges from 2640 to 2750 kg/m3. Where mass or mass density values (g, kg, or kg/m3) are given or measured, they must be multiplied by g(9.8 m/s2) to obtain weights or unit weights before performing stress calculations.

In the English system mass density values are virtually never used in geotechnical engineering and all work is performed in terms of unit weights (1b/ft3).

What Is Unit Weight Material?

What Is Unit Weight Material_

Unit weight material is also known as Specific material weight. Unit weight material is the weight of the material per unit volume.

As we know that the volume is identified in terms of liters or m3 and weight is measured in terms of Kg or KN.

The unit weight of materials is the weight of material/unit volume which means the Unit weight is expressed in Kg/L or KG/m3 or KN/m3.

For easy reference, we organized all the building materials unit weights in a table. This list is a collective effort. Give a thumbs up if you liked it. Bookmark the page and use the search if required.

FAQ

Unit Weight of Materials

Unit weight or specific weight of any material is its weight per unit volume that means in a unit volume, how much weight of the material can be placed. Volume is measured in litres or cubic meters, and weight is expressed in kg or kilo Newton.
