Microkatals to zeptokatals converter
Convert microkatals (µkat) to zeptokatals (zkat). Calculate any value, follow the unit-factor steps and check a conversion table.
Updated · How we checkUse a decimal point, such as 2.5. Enter a value in µkat; the result is in zkat.
Formula
Worked example
Convert 1 µkat to zkat:
1 µkat ≈ 1e+15 zkat
Multiply your µkat value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What microkatals measure
Microkatals (µkat) represent catalytic activity. One unit equals 10^-6 kat. One katal is catalytic activity expressed as one mole per second under specified assay conditions.
Reading the result in zeptokatals
Zeptokatals (zkat) represent catalytic activity. One unit equals 10^-21 kat. One katal is catalytic activity expressed as one mole per second under specified assay conditions.
Where this conversion helps
Normalize a catalytic activity measurement into a requested decimal scale. Catalytic activity depends on assay conditions. This converter does not relate activity to enzyme mass or concentration.
How the scale changes
The input unit has a factor of 1e-6 kat; the output unit has a factor of 1e-21 kat. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.
Reading very small or large results
Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
