The psi, or pounds per square inch, is a unit of pressure (P) using the foot-pound-second (FPS) system. To calculate psi, divide the force applied (F) with the area (A). Measure the force applied. Use an instrument such as a force gauge, spring scale or strain gauge. Make sure that the unit is in pounds. Convert the value if necessary.


Pounds per square inch (psi) is a unit of pressure most commonly associated with tire pressure for an automobile or bike tire. However, because pressure gauges are attached to most tire pumps, there's often very little need to calculate psi in this context.


Online calculator to convert kilopascals to pounds per square inch (kPa to psi) with formulas, examples, and tables. Our conversions provide a quick and easy way to convert between Pressure units.


Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2. In the foot-pound-second (FPS) system, the units are pounds per square inch, or psi.


Calculate the area of the ram used in the application: In order to get the psi to lbs multiplier, we need to calculate the area. The formula for this is area = pie X the radius 2 (A=πR 2). So we multiply π (3.14) by 6.25 inches (radius of 2.5 inches 2) to get 19.625 square inches. Formula used to calculate pounds:


Use the rule that there are 0.433 psi per foot of water to calculate the psi of an elevated water storage tank, or alternatively, the rule that every 2.31 feet of water creates 1 psi. Use the formula: P = 0.433 × h, where h is the height of the water surface in feet and P is the pressure in psi.


Therefore, if flow doubles, pressure has usually had to quadruple to affect the change in a flowing system. Manufacturers of different types of piping publish flow-pressure data about their products. You can use this data to calculate GPM from pounds per square inch (PSI).


How to Calculate the CFM of an Air Compressor By Soren Bagley. SAVE; CFM stands for cubic feet per minute. Oftentimes the true rate of an air compressor is misrepresented by manufacturers. Because of this, the only way to determine the real CFM of your air compressor is to test it yourself. ... You will need to record the psig (pounds per ...


Again like the weight of evidence and the information value, PSI seems to have it’s root in information theory. Let’s calculate the population stability index (PSI) for our population (we have already seen a histogram for this above).


Pressure is often listed as psi. The formula to measure pressure is Pressure equals force in pounds over the area in square inch. The written abbreviated formula is P= F/A.
