What does the prefix "Micro" denote?

The prefix "Micro" denotes a factor of 1/1,000,000, which is also expressed as 10^-6 in scientific notation. This means that when a unit is prefixed with "Micro," it indicates that it is one millionth of the base unit. For example, a micrometer (µm) is one millionth of a meter, highlighting the small scale represented by the "Micro" prefix. It's a standard measurement used in various scientific and engineering fields, including electrical systems and equipment, where precision at micro-level dimensions can be crucial. Understanding this prefix aids in grasping the magnitude of measurements and quantities encountered in technical contexts.
