Bacterial Doubling Time Calculator: Bacterial Growth Rate Conversions, Curve Fitting, and Growth Prediction

A free, browser-based calculator for working with bacterial growth rate parameters. Converts between doubling time and Malthusian growth rate parameter; fits growth curves to user-supplied optical density or cell count data to extract doubling time; and predicts bacterial population size over time from initial density and growth rate. Results include an annotated growth curve plot. No installation required. Hosted at doublingtime.phage.org.
