General semiconductorMVP
Scientific notation
Convert any number to scientific, engineering, and SI-prefix forms — handy for semiconductor dimensions and concentrations.
Inputs
Result
Enter values and calculate to see the result.
Interpretation
Enter a number — for example a feature size like 0.0000015 m.
Formula
a × 10ⁿ (1 ≤ |a| < 10)
Engineering notation restricts n to multiples of 3.
Variables
| Symbol | Variable | Unit |
|---|---|---|
| a | Mantissa (significand) | dimensionless |
| n | Exponent (power of ten) | integer |
Assumptions & validity
This tool assumes:
- Values are shown to 6 significant figures with trailing zeros trimmed.
- SI-prefix form is only shown for exponents within the y (10⁻²⁴) … Y (10²⁴) range; otherwise the engineering form is used.
Worked example
Input 0.0000015 (= 1.5 µm as a length).
Scientific 1.5 × 10⁻⁶ · Engineering 1.5 × 10⁻⁶ · SI 1.5 µ
