Pharmacopoeial units other than USP may be represented on the label as additional information. The following approximate conversion factors can be used to convert the activities of pancreatic enzymes into USP units (Scharpé et al. 1997):

For amylase: 1 Ph.Eur. Unit = 1 BP Unit = 1 FIP Unit ~ 4.15 USP Units

For lipase: 1 Ph.Eur. Unit = 1 BP Unit = 1 FIP Unit ~ 1 USP Unit

For protease: 1 Ph.Eur. Unit = 1 BP Unit = 1 FIP Unit ~ 62.5 USP Units
