Unit Weight of Different Building Construction Materials

 What is the Unit Weight and Why it is important?

Unit Weight is also known as Specific weight. Unit weight is the weight of the material per unit volume. As we know that the volume is quantified in terms of litres 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.
