| \(\large{ \rho_w }\) (Greek symbol rho) = water density by temperature | \(\large{\frac{lbm}{ft^3}}\) | \(\large{\frac{kg}{m^3}}\) |
| \(\large{ \rho_{H2O} }\) (Greek symbol rho) = normal density of water | \(\large{\frac{lbm}{ft^3}}\) | \(\large{\frac{kg}{m^3}}\) |
| \(\large{ T }\) = temperature of water | \(\large{ F }\) | \(\large{ F }\) |
| \(\large{ T_0 }\) = normal temperature of water | \(\large{ F }\) | \(\large{ F }\) |
| \(\large{ \alpha_v }\) (Greek symbol alpha) = volumetric thermal expansion coefficient (0.0002) | \(\large{ \frac{in^3}{in^3\;F} }\) | \(\large{ \frac{mm^3}{mm^3\;C} }\) |
