milli

"Milli-" is a prefix in the metric system denoting a factor of one thousandth (1/1,000). It is symbolized as "m". This prefix is widely used in various scientific, engineering, and everyday measurements to express quantities that are a fraction of the base unit.

For example:

• One millimeter (mm) is one thousandth of a meter.
• One milliliter (mL) is one thousandth of a liter.
• One milligram (mg) is one thousandth of a gram.

The use of "milli-" as a prefix is standardized in the International System of Units (SI) and is crucial for expressing smaller measurements in a precise and understandable way.
