Scientific Notation Calculator
Convert standard decimal numbers to scientific notation, E notation, and engineering notation, or convert a mantissa and exponent back to decimal form.
Use a decimal point, optional comma group separators, a sign, or E notation.
Convert numbers into scientific notation
The main English intent is conversion: users enter a standard number and expect form, E notation, and often engineering notation. The tool also converts a mantissa and exponent back to decimal form.
In scientific notation, 1 <= |a| < 10 and n is an integer exponent.
- Use decimal input such as 1234500 or 0.000045.
- Use comma group separators for readability, such as 1,234,500.
- Use E notation such as 1.5e10 when copying from code, spreadsheets, or calculators.
Scientific, E, and engineering notation
| Notation | Example |
|---|---|
| Scientific notation | |
| E notation | 1.2345e6 |
| Engineering notation | , with exponents in multiples of 3 |
