Calculators: Logarithm | Ratio | Doubling | Tenfold | Multifold

Multifold Calculator

Calculates, how often a multiplying with a factor has to occur, to get from one value to another. The calculation is done with the general logarithm to the base b, log_b.

Formulas: b=^x√c/a, c=a*b^x, x=log_b(c/a)

Start value a:
Base b:
End value c:
Tenfolds x:

Decimal places:

Insert three values, the fourth value will be calculated. The maximal value for the decimal places is 15.

Example: to get a thousandfold of a value, e.g. to get from 1 to 1000, it has to be fivefolded about 4.292 times.
