# 10 Examples of Scientific Notation

**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.

**4: Avogadro’s Number**

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.
