Your results
Scientific notation6.5 × 10^6
Calculation breakdown
- To scientific notation
- coefficient × 10^exponent, with 1 ≤ |coefficient| < 10
- From scientific notation
- coefficient × 10^exponent
Worked example
6,500,000 in scientific notation is 6.5 × 10^6.
Assumptions
- Zero is shown as 0 × 10⁰ as a special case.
- Only the direction you select is used; the other fields are ignored.
How this calculator works
This calculator converts a plain number into scientific notation (a coefficient between 1 and 10 multiplied by a power of ten), or converts a coefficient and exponent back into standard decimal form.
Frequently asked questions
What is scientific notation used for?
It's a compact way to write very large or very small numbers, commonly used in science and engineering.
What if I enter zero?
Zero is a special case and is shown as 0 × 10⁰ rather than causing an error.
Can I convert back from scientific notation?
Yes, switch the conversion direction and enter the coefficient and exponent to see the standard decimal number.
