Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in firearms. These terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively. In recent years, they have been replaced by the adoption of more modern piezoelectric pressure gauges that mor

There have been other means to test pressure, such as a copper crusher, or even lead crusher, but they are long retired means. There is no direct correlation between this antique pressure measurements to the modern Piezo Transducer. So while it is an interesting footnote it is no longer a useful measurement technique for modern ballistics.

Copper crusher gauges are the traditional means to routinely determine peak pressures in large caliber weapons. Most attractive in this method is its simplicity in use. Questionable is the precision in reading the pressure in view of the cumbersome gauge calibration practice which is prone to errors, especially in the low temperature regime.
