Generation Time Calculator
Calculate Generation Time
Find doubling time from initial and final population counts
Predict Final Population
Calculate expected population after a given number of generations
Formula
n = log₂(Nₜ / N₀). Generation time g = t / n. Growth rate k = n / t. Specific growth rate μ = ln(Nₜ / N₀) / t.
Frequently Asked Questions
What is generation time?
Generation time (doubling time) is the time required for a bacterial population to double in number during exponential growth. E. coli, for example, has a generation time of about 20 minutes under optimal conditions.
How do you calculate generation time?
Generation time g = t / n, where t is the elapsed time and n is the number of generations. n = log₂(Nₜ/N₀), which is the log base 2 of the ratio of final to initial population.
