Specific Weight

on . Posted in Classical Mechanics

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.

 

Specific weight formula

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

\( \rho =   \gamma \;/\; g \)

\( g =   \gamma \;/\; \rho \)

Symbol English Metric
\( \gamma \)  (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 \(ft\;/\;sec^2\) \(m\;/\;s^2\)
