How to Convert Katal to Enzyme Unit (U)

To convert from Katal (kat) to Enzyme Unit (U) (U), multiply the value by 60,000,000.

Formula: U = kat × 60,000,000

Reverse: kat = U × 1.666667e-8

Step-by-Step Example

Start with your value in Katal. For example: 5 kat
Multiply by the conversion factor: 5 x 60,000,000
The result is: 300,000,000 U

About Katal

The katal (kat) is a unit of catalytic activity. One katal equals 1 base unit. UnitConvertLab converts it against every other catalytic activity unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: catalytic activity calculations, engineering and science, education.

About Enzyme Unit (U)

The enzyme unit (u) (U) is a unit of catalytic activity. One enzyme unit (u) equals 1.666667 × 10^-8 base units. UnitConvertLab converts it against every other catalytic activity unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: catalytic activity calculations, engineering and science, education.
