Inches of Fluid ⮕ PSI

$Inches of Fluid to PSI Equation$
Plain Text Formula: (Inches of Liquid) * Specific Gravity of Liquid * Density of Water (kg/m³) * (1 (lb/in³)/27679.90471(kg/m³))= PSI (lb/in²)
CodeCogs/LaTex: \[(Inches\,of\, \:Liquid)*S.G.*Density\, of\, Water(\frac{kg}{m^{3}})*\frac{1\,(\frac{lb}{in^{3}})}{27679.90471\,(\frac{kg}{m^{3}})}=PSI(\frac{lb}{in^{2}})\]

PSI ⮕ Inches of Fluid

$PSI to Inches of Fluid Equation$
Plain Text Formula: PSI (lb/in²)* (27679.90471(kg/m³) / 1 (lb/in³))*(1/Density of Water (kg/m³))*(1/(S.G.))= Inches of Liquid
CodeCogs/LaTex: PSI(\frac{lb}{in^{2}})*\frac{27679.90471\,(\frac{kg}{m^{3}})}{(\frac{lb}{in^{3}})}*\frac{1}{Density\, of\, Water(\frac{kg}{m^{3}})}*\frac{1}{S.G.}=Inches\, of\,\: Liquid
