Worked example

38 U/L (middle of the reference range) = 0.633 µkat/L

Conversion formulas

µkat/L	µkat/L = U/L × 0.01667	U/L = µkat/L × 60

Good to know

Angiotensin-converting enzyme (ACE) is an enzyme activity, reported in U/L or in µkat/L.

µkat/L × 60 = U/L.
Values depend on age and on the method; this blood test is not the same as the ACE inhibitor drugs.

Reference range

Unit	Adults
µkat/L	0.15 – 1.117
U/L	9 – 67
