Computing Dynamic Pressure (Q)

Dynamic_{Pressure} = 0.5 * Density_{Air} * Velocity^{2}
Where:
Dynamic Pressure (Standard/US): lb/ft^{2} or pounds per square foot (psf)
Dynamic Pressure (Metric/SI): Pascals
Air Density (Standard/US): Slugs/ft^{3}
Air Density (Metric/SI): kg/m^{3}
Velocity (Standard/US): feet/sec (fps)
Velocity (Metric/SI): meters/sec
A F22 Raptor is supercruising at Mach 1.7 at 40,000 feet. What is the Dynamic Pressure at that speed/altitude combination?
According to Glenn Research Center’s AtmosModeler Simulator (LINK), that speed is 1,806 km/hr (501.66 m/sec) and the air density at that altitude is 0.3 kg/m^{3}.
The equation becomes:
0.5 * 0.3 * 501.66^{2} = 37,749.41 pascals
