WebAug 24, 2024 · It is standard to specify the titer as cells per cm 3 (i.e. per ml = 1000 µl). If 100 µl is plated rather than one cm 3, then the titer inferred using the counts and total dilution factor is on the basis of per 100 µl rather than per 1000 µl. To convert the inferred titer to the standard units, one simply multiplies the count by 10.
