Enzyme activity
2 U (µmol/min)

Activity = 10 µmol / 5 min = 2.00 U (µmol/min).

Volumetric activity
2 U/mL

About this calculator

One enzyme Unit (U) = 1 µmol of substrate converted per minute. Activity = µmol product ÷ time; divide by volume for U/mL. The SI katal (mol/s) is the alternative unit.
