The mega, giga and kilo prefixes are acquainted to many people even in countries in which imperial measurements are more not unusual, including the U.S., thanks to their utilization for measuring pc storage. For example, one Gigabyte is 1,000 bytes. These prefixes also have other usages in computing. Since the additives on Hardware Circuit Boards are so small, they are generally measured in micrometers or Microns.
