Doubling time formula example
WebThe doubling time in this case is 6.5 hours, or between 6 and 7 hours. If the bacteria doubled every six hours, then there would be 200 in six hours, 400 in twelve hours, 800 in eighteen hours, 1600 in twenty-four hours, 3200 in thirty hours, and 6400 in thirty-six hours. WebDoubling Time Formula. The doubling time formula is: doubling\ time=\frac{\ln(2)}{\ln(1+rate)} Where rate is the percentage increase you expect per period, expressed as a decimal (for example, 5% would be ".05"). Doubling time, then, is the number of those periods it'd take for a quantity to double.
