While CUP and LUP numbers were intended to be comparable to the crushing power of a given pressure, the numbers are not equivalent. Since a longer duration, lower pressure pulse can crush the cylinder as much as a shorter duration, higher pressure pulse, CUP and LUP pressures frequently register lower than actual peak pressures (as measured by a transducer) by up to 20 %.

Within firearms, chamber pressure is the pressure exerted by a cartridge case's outside walls on the inside of a firearm's chamber when the cartridge is fired. The SI unit for chamber pressure is the megapascal (MPa), while the American SAAMI uses the pound per square inch (psi, symbol lbf/in 2) and the European CIP uses bar (1 bar is equal to 0.1 MPa).
The SAAMI maximum average pressure (MAP) for this cartridge is 51,000 psi (351.6 MPa) piezo pressure measured with modern piezoelectric pressure gauges that more accurately measure chamber pressures or alternatively 46,000 CUP psi measured by the (outdated) deformation of a copper cylinder.

Since atmospheric pressure at sea level is around 14.7 psi (101 kilopascals), this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure ...
Stable employment is the hallmark of a middle-class family. The median household income for a middle-class family was $80,060 in 2023. Meanwhile, the poverty threshold for a family of four was ...
Even in the G-League, he’s played three regular-season games (he’s played seven in the tipoff tournament, which is the equivalent to the NBA Cup), so 10 total, shooting 43% in the three games ...
California officials said late Monday that the U.S. military did not enter the state and release a large flow of water, as President Donald Trump had earlier claimed in the latest back-and-forth ...
