ONE FORMULA, ONE ANSWER
Dynamic Pressure Calculator
Check dynamic pressure before estimating wind-tunnel loads and coefficients. Choose input units and calculate one value within the stated conditions.
Inputs
Calculations run in this browser. Scientific notation such as 1.2e-3 is supported. Do not group thousands.
Result
Dynamic pressure q
Enter values and select Calculate.
q = ρ V² / 2
Assumptions
Use ρ>0 and V≥0. Dynamic pressure differs from static and total pressure. In compressible flow, a Pitot total-minus-static pressure reading is not generally equal to this value.
Displayed values are floating-point approximations. Measurement uncertainty and design safety factors are not calculated.
