Logarithm Calculators

Evaluate a logarithm in a chosen base using MiniWebtool’s Log (Logarithm) Calculator. Select e, 10, 2, or a custom base to see steps, a graph, and comparisons with other bases.

Calculate common logarithms individually or in a batch using MiniWebtool’s Log Base 10 Calculator. It can also recover x from log10(x), with selectable display precision and steps connecting the logarithm to its power of ten.

MiniWebtool’s Log Base 2 Calculator finds the exponent to which two must be raised to produce a positive input. Worked explanations and visual references help connect binary logarithms with powers of two.

MiniWebtool’s Natural Log Calculator evaluates ln(x) for a positive input. Worked explanations, a graph, and related logarithm calculations show how the value connects to the exponential base e.
