Scientific Notation Calculator
Convert a number to scientific notation, or convert scientific notation back to a decimal number.
About the Sci. Notation Calculator
Scientific notation compactly represents very large or very small numbers as a value between 1 and 10 multiplied by a power of ten — essential in physics, chemistry, and engineering. This calculator converts a regular decimal number into scientific notation, or converts scientific notation back into a standard decimal.
How It Works
Converting to scientific notation, the calculator expresses the number using JavaScript's exponential notation, which normalizes it to a single leading digit followed by a decimal fraction and a power of ten. Converting from scientific notation, it parses the "e" notation format directly back into a plain decimal number.
Scientific Notation: N = a × 10^b, where 1 ≤ |a| < 10. Example format: 6.5e6 means 6.5 × 10⁶.
Example
Scenario: Converting 6,500,000 to scientific notation.
Result: 6.5000e+6, meaning 6.5 × 10⁶.
Assumptions & Limitations
- Uses the 'e' notation format (like 3.2e5) as both the input and output format for scientific notation, matching how calculators and programming languages commonly represent it.
- Assumes standard decimal input for the 'to scientific notation' direction.
- Extremely large or small numbers may already be displayed in scientific notation by the browser before conversion, which is expected behavior for numbers beyond typical decimal display ranges.
