How much is 1 Giga (G) in scientific notation?

1 Giga (G) is equivalent to one billion, which is expressed in scientific notation as 1 x 10^9. The prefix "Giga-" denotes a factor of one billion (10^9), which is a standard unit in the International System of Units (SI) used to represent large quantities, particularly in fields like computing and telecommunications. Thus, when you see "Giga," it indicates a multiplication factor of 1,000,000,000, or 10^9 in scientific terms.

This understanding is crucial when dealing with measurements related to data (like gigabytes) or other quantities that frequently employ the metric prefixes. The other choices reflect different orders of magnitude: 10^3 is one thousand, 10^6 is one million, and 10^12 is one trillion, which are not applicable for the Giga prefix.
