How much does the prefix 'micro' correspond to in powers of ten?

The prefix 'micro' corresponds to a factor of (10^{-6}) in the metric system. This means that when a unit is prefixed with 'micro', it indicates that the unit is one-millionth of the base unit. For instance, a micrometer is one-millionth of a meter, and a microgram is one-millionth of a gram. Understanding the metric prefixes is crucial in fields such as chemistry and biology, as it allows for accurate and precise measurements across different scales. Each metric prefix has a specific power of ten associated with it, and 'micro' being (10^{-6}) is well-established in scientific literature. Thus, the correspondence of 'micro' to (10^{-6}) directly validates the answer given.
