<br />
The '''milli-''' (symbol '''m''') is a unit prefix in the [[metric system]] denoting a factor of one thousandth (10<sup>-3</sup>) of the base unit. It is used in the [[International System of Units]] (SI) and is one of the most commonly used prefixes in scientific and technical fields.<br />
<br />
==History==<br />
The prefix milli- was adopted in 1795, derived from the [[Latin]] word "mille," meaning "thousand." It was introduced as part of the metric system, which was developed in France during the late 18th century. The metric system was designed to be a universal and standardized system of measurement based on the decimal system.<br />
<br />
==Usage==<br />
The milli- prefix is widely used in various scientific and engineering disciplines. It is applied to a variety of units to indicate a thousandth of the base unit. Some common examples include:<br />
<br />
* [[Millimeter]] (mm) - A unit of length equal to one thousandth of a [[meter]].<br />
* [[Milliliter]] (mL) - A unit of volume equal to one thousandth of a [[liter]].<br />
* [[Milligram]] (mg) - A unit of mass equal to one thousandth of a [[gram]].<br />
* [[Milliampere]] (mA) - A unit of electric current equal to one thousandth of an [[ampere]].<br />
<br />
==Applications==<br />
The milli- prefix is particularly useful in fields where precise measurements are required. For example, in [[medicine]], dosages of medications are often measured in milligrams to ensure accuracy and safety. In [[engineering]], components such as resistors and capacitors may be specified in milliohms or millifarads, respectively, to achieve the desired electrical characteristics.<br />
<br />
==Conversion==<br />
To convert a measurement from a base unit to a milli- unit, multiply the base unit by 10<sup>-3</sup>. Conversely, to convert from a milli- unit to a base unit, multiply by 10<sup>3</sup>.<br />
<br />
==Examples==<br />
* 1 meter = 1000 millimeters<br />
* 1 liter = 1000 milliliters<br />
* 1 gram = 1000 milligrams<br />
* 1 ampere = 1000 milliamperes<br />
