Specific weight, abbreviated as \( \gamma \) (Greek symbol gamma), also called unit weight, is the weight per unit volume of a substance. It is defined as the force exerted by gravity on a unit volume of a material.

\( \gamma \;=\; \rho \cdot g \) (Specific Weight) \( \rho \;=\; \dfrac{ \gamma }{ g }\) \( g \;=\; \dfrac{ \gamma }{ \rho }\) |

| \( \gamma \) (Greek symbol gamma) = Specific Weight | \(lbf\;/\;ft^3\) | \(N\;/\;m^3\) |
| \( \rho\) (Greek symbol rho) = Density | \(lbf\;/\;ft^3\) | \(kg\;/\;m^3\) |
| \( g \) = Gravitational Acceleration | \(ft\;/\;sec^2\) | \(m\;/\;s^2\) |
