Dynamic & Stagnation Pressure

Calculate the dynamic pressure ½ρv² of a moving fluid and the stagnation pressure, free online.

Velocity (m/s)

Density (kg/m³; air 1.225, water 1000)

Static pressure (kPa) — optional (optional)

About this calculator

Dynamic pressure q = ½ρv² is the kinetic energy per unit volume of a moving fluid. Total (stagnation) pressure = static pressure + q. Pitot tubes measure it, and it also gives the wind load on a surface (force = q × area × drag coefficient).
