## About Decimal to Scientific Notation Converter

The 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 accommodate values too large or small to be conveniently written in standard decimal notation.

In scientific notation, all numbers are written like this:

a × 10b

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 2.99792458×108 ≈ 3×108 m/s.

2. 0.00345 would be written as 3.45×10-3 in scientific notation.
