Introduction to Aeronautics Lessons

Now convert the answer above from PSI (Pounds per square inch) to PSF (lbs per square foot): C. APPENDIX C - Unit Conversion MPH to FPS. A standard measurement for velocity is MPH (miles per hour). In aeronautics we often have to convert to FPS (feet per second) to keep the units in velocity and pressure, PSF (pounds per square foot) the same. ................
