Growths on the surface of the eye can be unsightly and frightening. Most growths on the eye, which often occur as people age, pose no threat to health or vision and aren&rsquo;t cancers.
The unit of measure for static pressure is often inches of water (in. water). one inch of water is the suction needed to draw water up a straw one inch. pound per square inch static pressure (1 psi) is equal to 27.7 in. water static pressure. static pressure is given as Pascals (Pa).
Standard Pressure = 14.7 psi (Pounds per square inch) or 1.5 mega Pascal. Note: a Pascal is a very small unit of pressure equal to the force exerted by 1 Newton acting over an. area of 1 square meter.
