## About This Tool

The online Decimal to Scientific Notation Converter is used to convert a number from ordinary decimal notation into scientific notation.

## Scientific Notation

Scientific notation (also called standard form or exponential notation) is a way of writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.

In scientific notation all numbers are written like this:

a × 10^{b}

where the exponent b is an integer, and the coefficient a is any real number (called the significand or mantissa).

In normalized scientific notation, the exponent b is chosen such that the absolute value of a remains at least one but less than ten (1 ≤ |a| < 10).

## Examples

**1.** The speed of light (299792458 m/s) in scientific notation is 2.99792458×10^{8} ≈ 3×10^{8} m/s.

**2.** 0.00345 would be written as 3.45×10^{-3} in scientific notation.
