Easily calculate logarithms with our fast and accurate Log Calculator from Calculator Hub HQ — supporting log base 10, natural log (ln), and custom log bases.
The Log Calculator from Calculator Hub HQ allows you to quickly and accurately compute logarithmic values for any number. Whether you’re a student solving equations, a data scientist analyzing exponential trends, or an engineer working with scientific data, this tool is designed for speed, accuracy, and ease of use.
Our calculator supports:
A logarithm is the inverse operation of exponentiation. If a^b = c, then log base a of c = b. It’s a fundamental concept used across algebra, calculus, computer science, and statistics.
Examples:
log₁₀(1000) = 3 because 10³ = 1000ln(e²) = 2 because e² = e²The tool provides instant results and is perfect for solving logarithmic equations, understanding exponential decay or growth, and simplifying complex formulas.
Log base 10 (common logarithm) is the logarithm where the base is 10. Example: log₁₀(100) = 2.
The natural log is a logarithm with base e (Euler’s number ≈ 2.718). Example: ln(e) = 1.
Yes! Our tool supports any positive real number as the base (except 1).
