💡 What Is a Natural Logarithm?
The natural logarithm, or ln, is the logarithm with base e (approximately 2.718). In simple terms, the natural log tells you the power to which you’d raise e to get a given number. For example, ln(1) = 0 and ln(e) = 1. Algebra, calculus, physics, biology, and economics all rely on natural logs — especially when dealing with exponential growth or decay.
By using this calculator, you can skip complex math steps and get answers instantly, helping you focus on understanding concepts and solving real problems.
