Pounds per square in is a unit for measuring pressure (force per unit area). Absolute pressure is the pressure (eg in a gas) compared to a vacuum, where the pressure is zero. Often we measure the pressure relative to the atmosphere, which has a pressure of about 14.7 pounds per square inch (psi). This relative pressure is called the gauge pressure. So a (gauge) pressure of 30 psi in a car tyre is really an absolute pressure of 14.7 + 30 = 41.7 psi. See http://en.wikipedia.org/wiki/Pressure http://wiki.answers.com/Q/What_is_absolute_pressure
Thrust is usually measured in 'pounds per square inch' or psi.
They are not the same. Pounds is a measurement of weight. Square Feet is a measurement of Area. Some references to "pounds" really is meant to be "pounds per Square inch" which is a measurement of Pressure (or force). Maybe you mean converting "pounds per square inch" to "pounds per square feet"?? You need to be more specific and check your facts of the problem.
The number of Pounds per Square Inch (PSI) for the Tensile strength.
It is the strength in pounds per square inch of a material at which it will be pulled apart.
PSI stands for pounds per square inch, which is a common unit of measurement for air pressure. It represents the amount of force exerted by the air on a given area. It is commonly used to measure tire pressure in vehicles.
Psi on tire pressure stands for PSI = pounds per square inch.
"PSI" stands for "pounds per square inch," which is a unit of pressure commonly used in industries like automotive and manufacturing to measure the pressure of gases and liquids.
What does psi mean when shown as a value on a oxygen tank? Pounds per square inch.
psi means pounds per square inch. It is referring to the pressure used for wound irrigation.
psi is Pounds per Square Inch, and is a measure of the pressure inside the boiler.
2 psig stands for 2 pounds per square inch gauge, which is a unit of pressure measurement that represents the pressure relative to the atmospheric pressure at the location of measurement. In this case, it indicates a pressure that is 2 pounds per square inch above the ambient atmospheric pressure.
