Log Calculator
This log calculator finds the logarithm of any number in both common forms at once: the base-10 logarithm (log) and the natural logarithm (ln, base e). Just enter a number and it instantly returns both results: the base-10 log tells you what power of 10 produces your number (for example, log 1000 = 3), while the natural log gives the equivalent using the constant e ≈ 2.718 (ln 1000 ≈ 6.908).
Logarithms are essential for working with quantities that span huge ranges or grow exponentially, supporting the pH scale, the Richter scale for earthquakes, decibels for sound, and compound growth and decay. It’s built for students learning algebra, precalculus, or chemistry, teachers demonstrating the concept, and anyone in science, engineering, or finance who needs a quick, accurate logarithm.
