About This Tool
The online Natural Log Calculator is used to calculate the natural logarithm of a number x, which is generally written as ln(x) or loge(x).
The natural logarithm is the logarithm to the base e
(Euler's number, approximately equal to 2.718281828). It is generally written as ln(x), loge
(x) or sometimes, if the base of e is implicit, as simply log(x). It is often used in mathematical analysis, physics, chemistry, statistics, economics, and some engineering fields.
