## weight DENSITY formula

 $$\large{ W_{\rho} = \frac{m \; g}{g_c} }$$

### Where:

 Units English Metric $$\large{ W_{\rho} }$$  (Greek symbol rho) = weight density $$\large{\frac{lbf-in}{ft^3}}$$ $$\large{\frac{kg-mm}{m^3}}$$ $$\large{ g }$$ = gravity $$\large{\frac{ft}{sec^2}}$$ $$\large{\frac{m}{s^2}}$$ $$\large{ g_c }$$ = gravity conversion constant $$\large{in^4}$$ $$\large{mm^4}$$ $$\large{ m }$$ = mass $$\large{lbm}$$ $$\large{kg}$$
