Scientific Notation Converter
Convert between standard numbers and scientific notation (a × 10ⁿ).
Scientific notation writes a number as a value between 1 and 10 times a power of ten — for example 149,600,000 = 1.496 × 10⁸. Accepts × 10^n or e-notation (1.496e8). Runs in your browser.
Convert a number into scientific notation — a value between 1 and 10 multiplied by a power of ten — or expand scientific notation back into a standard number. For example 149,600,000 becomes 1.496 × 10⁸. It accepts both '× 10^n' and e-notation (1.496e8). Useful for science, engineering and very large or small numbers. Runs in your browser.
How to use the Scientific Notation Converter
- Choose standard → scientific or scientific → standard.
- Enter the number or the notation.

Frequently asked questions
What is scientific notation?
A way of writing numbers as a coefficient between 1 and 10 times a power of ten, like 6.02 × 10²³. It keeps very large or very small numbers compact and readable.
What is e-notation?
A shorthand used by calculators and computers where '× 10^' is replaced by 'e' — so 1.496 × 10⁸ is written 1.496e8. This tool accepts both forms.
