Scientific & Engineering Notation Converter
Convert between standard decimals, scientific notation (1.23e+8), and engineering metric prefixes (nano to tera).
About This Tool
The Scientific & Engineering Notation Converter converts numbers between standard decimal format, normalized scientific notation (a × 10^b where 1 ≤ |a| < 10), engineering notation (where exponents are multiples of 3), and SI metric prefixes.
Key Features
How to Use This Tool
- Enter any decimal or scientific number (e.g. 0.000045, 125000000, 3.4e-5).
- Instantly view the standard, scientific, engineering, and metric prefix representations.
Why Use This Tool
- Format scientific formulas and physics constants.
- Work with electronic component values (capacitors in pF/nF/uF, resistors in kΩ/MΩ).
Pro Tips
- Engineering notation restricts exponent powers to multiples of 3 (10³, 10⁶, 10⁻³, 10⁻⁶), corresponding directly to SI metric prefixes.
Frequently Asked Questions
What is the difference between Scientific and Engineering notation?
Scientific notation has exactly one non-zero digit before the decimal point (e.g. 4.5 × 10^7). Engineering notation requires the exponent to be a multiple of 3 (e.g. 45 × 10^6), aligning with metric prefixes like mega (M) and micro (µ).
What does 'e' mean in numbers like 1.25e+8?
The 'e' stands for 'exponent of 10'. 1.25e+8 means 1.25 × 10^8 (125,000,000).
