About these measurements
Catalytic activity expresses the rate of a catalyzed reaction in moles per second.
The base reference used here is the katal. One centikatal is 0.01 base units; one petakatal is 1e+15 base units.
Important distinctions
Assay conditions must match before comparing enzyme measurements.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
