About Scientific Notation Converter
The Scientific Notation & Engineering Notation Converter transforms numbers between Standard Decimal Form, Scientific Notation ($a \times 10^b$ where $1 \le |a| < 10$), Engineering Notation (powers of 3), E-Notation (`1.23e+8`), and SI Metric Prefixes (kilo, mega, giga, micro, nano).
How to Use Scientific Notation Converter
Step 1
Enter any number in standard decimal, scientific ($1.5e8$), or fraction format.
Step 2
Inspect the converted scientific, engineering, and SI prefix representations.
Step 3

Key Terminology & Definitions
Scientific Notation ($a \\times 10^b$)
A way of expressing numbers that are too large or too small, written in the form $a \\times 10^b$, where the coefficient $a$ satisfies $1 \\le |a| < 10$ and $b$ is an integer.
Engineering Notation
A version of scientific notation where the exponent $b$ is strictly restricted to multiples of 3, aligning with standard SI metric prefixes.
