Scientific Notation Converter

Convert numbers between standard decimal format, scientific notation (`1.23 × 10^5` / `1.23e5`), and engineering notation (exponents in multiples of 3).

Why Use This Converter?

• Science & Physics: Convert extremely large or small measurements (astronomical distances, subatomic particles).
• Engineering: Format numbers into engineering notation where exponents match SI prefixes (kilo 10^3, mega 10^6, micro 10^-6).
• Math Homework: Verify scientific notation conversions and significant figures.

How to Use

1. Enter a decimal number (e.g., `0.0000123`) or E-notation string (`1.23e-5`).
2. View formatted outputs in Scientific Notation, E-Notation, and Engineering Notation.
3. Copy the formatted output string.

Real Conversion Example

Input (TEXT):

1230000

Output (TEXT):

Scientific Notation: 1.23 × 10^6
E-Notation: 1.23e+6
Engineering Notation: 1.23 × 10^6

Important Technical Details & Mechanics

• BigNumber Precision: Handles high precision without standard JavaScript floating-point truncation.
• Engineering Exponent Steps: Engineering mode constrains exponents to multiples of 3 (10^3, 10^6, 10^9, 10^-3, 10^-6).
