petakatal to megakatal
Convert petakatal (Pkat) to megakatal (Mkat). Use an editable catalytic activity converter, conversion formula, and reference table.
1 Pkat = 1,000,000,000 Mkat
Conversion formula
One petakatal equals 1,000,000,000 megakatal. Multiply your value in petakatal by this factor to get megakatal. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 petakatal:5 × 1,000,000,000 = 5,000,000,000 Mkat

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 petakatal is 1e+15 base units; one megakatal is 1,000,000 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.
