Specific Weight
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.

\( \gamma = \rho \; g \) (Specific Weight) \( \rho = \gamma \;/\; g \) \( g = \gamma \;/\; \rho \) |

\( \gamma \) (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 | \(ft\;/\;sec^2\) | \(m\;/\;s^2\) |
