What would the unit value of a milli be in decimal?

The term "milli" is a metric prefix that denotes a factor of one thousandth. In decimal form, one milli equals 0.001. This means that when you see a measurement preceded by "milli," such as millimeter or milligram, you can understand that it represents a fraction of the base unit, reduced by a factor of 1,000.

In this case, the correct answer is tied directly to this definition. A milli value is useful in many fields, particularly in pharmacology and medicine, where precise measurements are critical. Recognizing this metric prefix will help you convert between units efficiently and understand the scale of measurement that is often used in scientific contexts.
