A soil has a dry density of 1.9Mg/ml What is its dry unit weight?


Pd = ^=1.90Mg/m3 Quick approximation

If we assume the engineering approximation that 7W = 10 kN/m3 (instead of 9.81), then in the previous example:

Hence, given a density in Mg/m3, the unit weight (in kN/m3) is found by multiplying by ten.
