 Pound-force per square inch - Wikipedia, the free encyclopedia
Pound-force per square inch (symbol: lbf/in²) is a non-SI unit of pressure.
psia (pounds-force per square inch absolute) - gauge pressure plus local atmospheric pressure.
At 1 lbf/in², a force of one pound-force is applied to an area of one square inch.

 UK's National Pressure Standards - Is it pressure or vacuum?
Its magnitude depends on the force of the impacts over a defined area; hence, for example, the Newton per square metre (given the special name pascal) and the traditional (but obsolete!) unit pound-force per square inch.
Broadly, if the force on the walls of the containing vessel is sufficient to permit its measurement directly, we are dealing with pressure technology but if the force is too small for direct measurement and has to be indirectly inferred, we are in the realm of vacuum technology.
Thus the word pressure is correct when referring to the entire range of 'force per unit area' measurements, although at extremely low pressures the concept of molecules exerting a force becomes more abstract.

It is expressed in pound-force per square inch or psi in the U.S. Customary system.
Pressure is defined as the force exerted by a fluid at rest per unit area on which the force acts.
Other units of pressure include inches of water, inches of mercury, millimeters of mercury, atmospheres, torr, bars, and millibar.

Pressure is still sometimes expressed in kgf/cm² or grams-force/cm² (sometimes as kg/cm² and g/cm² without properly identifying the force units).
It is defined as the magnitude of the normal force divided by the area over which the normal force acts.
Although the force applied to the surface is the same, the thumbtack applies more pressure because the point concentrates that force into a smaller area.

A kilogram force is the weight of a kilogram of mass (kg) and is equal to 9.807 newtons (N) or 2.2046 pounds.
Both ratios are non-dimensional, and they may be equal if the volumes and forces are measured under identical sets of conditions such as gravity acceleration, air buoyancy and temperature.
Thus, a pound mass (lbm) is a mass that weighs one pound.

Most prototypes currently have 5,000 psi (pound-force per square inch) tanks, which provides a range of between 100 miles and 180 miles.
But a number of manufacturers, including Nissan, Honda, and of course DaimlerChrysler, are focusing on raising the pressure in the tanks, to force the hydrogen molecules closer together.
General Motors has also been experimenting with solid metal hydride materials, metal alloys that release hydrogen when they’re heated.

 UK's National Pressure Standards - Pressure units
In the fullness of time, when their second-class nature is more widely appreciated, market forces will doubtless operate and naturally cause end users to abandon them.
The end is in sight for the so called ‘manometric’ pressure units, such as inches of water, millimetres of water, inches of mercury and millimetres of mercury, but a large part of the pressure community seems unaware of the potential problems in store for them.
In order to encourage the demise of non-SI units, whose definitions are becoming inadequate for the most precise measurement of pressure, there is international effort to exclude them from conversion tables or, in the meantime, restrict the precision of newly published conversion factors.
