The millikatal measures the catalytic activity of enzymes and other catalysts, representing 10⁻³ katals. One millikatal indicates a catalyst can facilitate the reaction of one millimole of substrate per second. It is used in industrial biochemistry and enzyme kinetics to quantify the throughput of biological reactors.

The new yeast strain boosted the fermentation rate to nearly four millikatals per batch.
