Scientific Notation Converter

About This Tool

This tool converts numerical inputs to canonical scientific notation (mantissa × 10^exponent) and can also revert scientific notation back to decimal form. It is designed for researchers, engineers, and students who require compact, unambiguous representations for data tables, reports, or calculation pipelines. The approach is data-agnostic and language-agnostic, focusing on numeric correctness and reproducibility.
Conceptually, the system parses a value, determines its magnitude with a base-10 operation, and normalizes it so that the mantissa lies in the [1,10) interval while recording the exponent. It supports inputs like 0.00056, 12345, or 5.67e3, and provides outputs as mantissa, exponent, and a standard notation string that can be displayed or logged in calculations.
Advanced usage includes setting a fixed precision in significant figures, which controls how many digits appear in the mantissa. It also supports locale-aware parsing and returns robust validation feedback for invalid inputs. The tool adheres to SI notation conventions and is useful for data preparation, scientific reporting, and educational demonstrations.
