New unit request: CFU/100 mL

QUDT already has Colony Forming Unit. It would be great to have it scaled to the volume (per 100 mL).

Would you say a unit:CFU is a dimensionless Count?

Would you say a unit:CFU is a dimensionless Count?

Yes, it refers to number of occurences in a sample. So while CFU is comparable within an experiment (e.g. lab uses one model of petri dish, so they always have same volume), it is not comparable across different experiments.
