MihsabaHow to use
Scientific notation writes a value as a coefficient times a power of ten. Enter ordinary decimals or E notation such as 6.022e23, optionally perform arithmetic with a second value, and view scientific, E and engineering forms together.
- Enter the first value as a decimal or E-notation number.
- Choose convert-only or an arithmetic operation and provide the second value if needed.
- Calculate to view equivalent scientific, E and engineering forms.
How it is calculated
Example
Example: 0.00042 is 4.2 × 10^-4 and 4.2e-4. In engineering notation it is 420 × 10^-6 because the exponent must be divisible by three.
Important notes
The calculator uses JavaScript floating-point numbers, so it is intended for general calculation rather than arbitrary-precision decimal or symbolic work. Values outside the supported numeric range are rejected. Significant-figure rules are not applied automatically.
Frequently asked questions
What is E notation?
It is a keyboard-friendly form of ×10^n; for example 3.5e6 means 3.5 × 10^6.
How is engineering notation different?
Scientific notation normalizes the coefficient to magnitude 1–10; engineering notation makes the exponent a multiple of three.
Can I divide by zero?
No. The calculator returns an error instead of an undefined result.
Is this calculator free?
Yes. It is free to use and requires no account.
