Formula
Doublings = log₂(Nf/Ni). Td = t · ln2 / ln(Nf/Ni). Growth rate μ = ln2 / Td.
Domande Frequenti
What counts as "doubling time"?
The time required for a cell population to double in number under exponential growth. It assumes constant, unrestricted growth.
When does this break down?
Near confluence, under stress, or with non-exponential kinetics. Use for early log-phase data.
