Fluid Depth, Density, Gravity & Pressure Calculator
Solve for any variable in the hydrostatic equation P = ρgh.
Fluid Depth Density Gravity Pressure Calculator computes hydrostatic pressure using P = rho*g*h. Hydrostatic pressure is the pressure caused by the weight of fluid above a point; it increases with fluid density, gravitational acceleration, and vertical depth. Density describes mass per unit volume, gravity sets the body force acting on that mass, and depth is measured vertically below the fluid surface rather than along a sloped path. Gauge pressure measures pressure above the surrounding atmosphere, while absolute pressure includes atmospheric pressure as well. This tool is useful for wells, tanks, underwater design, and scuba or pipeline checks, but moving fluids, compressibility, temperature variation, and vessel geometry can require more detailed analysis.
