Void Ratio

Void ratio, abbreviated as e, a dimensionless number, is the ratio of the volume of voids to the volume of solids.

 

Void Ratio formula
\(\large{ e = \frac {V_v} {V_s } }\)
Symbol	English	Metric
\(\large{ e }\) = void ratio	\(\large{dimensionless}\)
\(\large{ V_s }\) = volume of solids	\(\large{ft^3}\)	\(\large{m^3}\)
\(\large{ V_v} \) = volume of voids	\(\large{ft^3}\)	\(\large{m^3}\)
