Microbiology calculators
Quantifying a microbial culture: colony-forming units from a plate count, cell density estimated from OD600, and the specific growth rate and doubling time from two measurements in exponential phase.
Plate counts are checked against the countable range, and the OD600 conversion is treated as the empirical estimate it is, with a conversion factor you set for your own organism and instrument.
