Convert a number into scientific notation by calculating its coefficient and power of ten.
Fill in the details and click Calculate to see your results.
Scientific notation is useful for very large or very small numbers.
For a non-zero number x, the exponent is the floor of log base 10 of its absolute value, and the coefficient is x divided by 10 raised to that exponent.
| Number | 12345 |
| Scientific Notation Coefficient | 1.2345 |
| Power of 10 | 4 |
| 10 to the Power | 10,000 |
The coefficient is 1.2345 and the exponent is 4, so the form is coefficient × 10^exponent.
Try this example →| Number | 0.0045 |
| Scientific Notation Coefficient | 4.5 |
| Power of 10 | -3 |
| 10 to the Power | 0.001 |
The coefficient and exponent identify the equivalent power-of-ten representation.
Try this example →It expresses a non-zero number as a coefficient multiplied by a power of ten.
Yes. Small numbers use negative powers of ten.
Zero does not have a unique standard scientific-notation exponent, so this calculator is intended for non-zero inputs.
