Abstract
The usual atmospheric pressure used for calibration is 760 mmHg (100 kPa or 14.7 psi), which is the standard at sea level. Negative pressure is any pressure that is less than atmospheric, or zero, on the pressure gauge. A vacuum force can thus be described as a negative pressure; suction is the application of that negative pressure, and relates to the movement of gas, fluids, or solids so caused.
