Algebra
Logarithm Calculator
Compute the logarithm of any positive number in any positive base using the change-of-base formula. Logarithms are the inverse of exponentiation and the natural language of orders of magnitude, sound intensity, pH, earthquake energy, and algorithmic complexity.
Fill in the required fields to see your result.
Math
Scientific Notation Converter
Convert numbers between standard decimal form and scientific notation (a × 10ⁿ, with 1 ≤ |a| < 10). Essential in science, engineering, and any context where values span many orders of magnitude — atomic masses, astronomical distances, financial figures, computer-memory sizes.
