The Scientific Notation Converter converts between decimal form and scientific notation (e.g. 1.23 × 10^4 or 1.23e4). Useful for very large or very small numbers in science and engineering.
What is Scientific Notation?
Scientific notation writes a number as a mantissa times a power of 10 (e.g. 1.23 × 10^4 = 12300). The tool accepts both decimal input and scientific form (1.23e4 or 1.23 × 10^4) and converts in either direction.

Frequently Asked Questions
What is this tool used for?
It converts between decimal form and scientific notation (mantissa × 10^exponent), useful for very large or small numbers.
What input formats are accepted?
Decimal: any number. Scientific: e.g. 1.23e4 or 1.23 × 10^4. Both positive and negative are supported.
Are there precision limits?
JavaScript number precision applies (about 15–17 significant digits). Very large or tiny values may lose precision.
Is conversion done on a server?
No. All conversion runs in your browser.
When should I use it?
Use it for science, engineering, or when reading or writing numbers in standard form.
Why does scientific to decimal fail?
Use a valid format: 1.23e4 or 1.23 × 10^4 (with × or * and ^). Ensure exponent is an integer.
