What is 10 to the 9th power?

10 to the 9th power, often written as 10<sup>9</sup>, is equal to 1,000,000,000 (one billion).

  • It's a common way to represent a very large number.

  • In the metric system, 10<sup>9</sup> is the prefix "giga". For example, a gigabyte (GB) is 10<sup>9</sup> bytes.

  • In computing, it is sometimes used (though less precisely) to refer to 2<sup>30</sup> = 1,073,741,824, especially in older systems or when referring to memory or storage size. This is because powers of 2 are important in binary systems.

  • Financial figures are sometimes expressed in billions.

  • Population statistics may be reported in the billions, such as the global population.

  • Scientific measurements can utilize 10<sup>9</sup> to represent large quantities. For example, distances in space.

  • The term "billion" is equivalent to 10<sup>9</sup> in the short scale system (used in most English-speaking countries).

  • The speed of processors are often measured in gigahertz (GHz), which is 10<sup>9</sup> hertz.

  • Electricity consumption or generation of a power plant is measured in gigawatts which is 10<sup>9</sup> watts.
