Cell Doubling Time Calculator
How to calculate cell doubling time
- Type the starting count and the final count.
- Type the hours between the two counts.
- The doubling time appears with the growth rate, the number of doublings and the doublings per day.
Frequently asked questions
What is the formula?
Doubling time = time × ln 2 / ln(final count / starting count).
Does it work for bacteria?
Yes, for any population in exponential growth. Counts taken in the lag or stationary phase give a longer doubling time.
Can I see the growth curve?
The Bacterial Growth Simulator grows a culture on a 3D plate with the doubling time you set and plots the count on a log scale up to the carrying capacity.
