How to Use the Scientific Notation Converter
Scientific notation expresses very large or very small numbers as a × 10ⁿ, where 1 ≤ |a| < 10. It's widely used in science, engineering, and astronomy to keep numbers compact and readable.
- Standard → Scientific: e.g. 0.000123 → 1.23 × 10⁻⁴
- Scientific → Standard: e.g. 3.5 × 10⁶ → 3,500,000
- Standard coefficient range: 1 ≤ |a| < 10
Examples: Speed of light 299,792,458 m/s → 2.998 × 10⁸ m/s. Atom diameter 0.0000001 mm → 1 × 10⁻⁷ mm.
Frequently Asked Questions
Does this work with negative numbers?
Yes. Negative numbers are converted the same way. Example: -0.005 = -5 × 10⁻³.
What if my coefficient is outside 1–10?
The converter automatically adjusts the input to standard scientific notation form (1 ≤ |a| < 10).
Can I convert zero?
Zero cannot be expressed in scientific notation. Please enter a nonzero value.
