# 10 Examples of Scientific Notation

October 9, 2023 written by Rida Mirza

Scientific notation is a way to express numbers that are too large or small to conveniently write in decimal form. It is written as the product of a number between 1 and 10 and a power of 10.

In this article, we will discuss ten examples of scientific notation in mathematics.

## Examples of Scientific Notation

These are 10 examples of scientific notation.

### 1: Speed of Light

Speed of light in a vacuum is approximately 299,792,458 meters per second. In scientific notation, it is written as 2.99792458 x 10^8 m/s.

### 2: Mass of Earth

Mass of the Earth is roughly 5,972,190,000,000,000,000,000,000 kilograms. In scientific notation, it is expressed as 5.97219 x 10^24 kg.

### 3: Planck’s Constant

Planck’s constant, a fundamental constant in quantum physics, is approximately 6.62607015 × 10^-34 J·s.

Avogadro’s number, representing the number of atoms or molecules in one mole of a substance, is about 6.02214076 × 10^23 mol^-1.

### 5: Gravitational Constant

Gravitational constant, denoted as G, is approximately 6.674 × 10^-11 m^3 kg^-1 s^-2.

### 6: Astronomical Distances

Astronomical distances, such as the distance from Earth to the nearest star, Proxima Centauri, is roughly 4.22 × 10^16 meters.

### 7: Size of an Atom

Size of a typical atom is on the order of 0.1 nanometers, expressed as 1 × 10^-10 meters.

### 8: Electron Charge

Elementary charge of an electron is approximately -1.602176634 × 10^-19 coulombs.

### 9: Speed of Sound

Speed of sound in dry air at room temperature is roughly 343 meters per second, written as 3.43 × 10^2 m/s.

### 10: Euler’s Number

Euler’s number (e), a mathematical constant, is approximately 2.718281828459045. In scientific notation, it is expressed as 2.718 x 10^0.
