What is a giga unit?

A giga unit is a metric prefix that denotes a factor of one billion, or (10^9). It is commonly used in various scientific and technical fields to quantify large amounts, such as gigabytes for data storage or gigahertz for frequency. The prefix "giga" comes from the Greek Word "gigas," meaning giant. In the International System of Units (SI), it helps simplify the representation of large numbers.
