natural log

Logarithm using e

Natural log is the logarithm with base *e* (approximately 2.718), written ln.

It answers the question: to what power must *e* be raised to produce this number?

The natural log appears throughout mathematics, physics, and engineering because *e* arises naturally in processes involving continuous growth or decay: The natural log of 1 is 0.

Often shortened to "natural log" in speech even when written as ln.
