Weight density or specific weight is defined as the weight per unit volume of a liquid at a standard temperature and pressure. Weight density or specific weight is usually denoted by w. Weight density or specific weight is expressed in kN/m3 or N/m3 or N/mm3.
Mathematically, weight density or specific weight,
w = ρ.g
Note: For water, w = 9.81 kN/m3 = 9.81 x 103 N/m3 = 9.81 x 10-6N/mm3.
