OverviewMethodologyComparing unitsCUP and LUP pressures vs. transducer pressuresExternal links

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 In recent years, they have been replaced by the adoption of more modern piezoelectricpressure gauges that more accurately measure chamber pressures and generally give significa
