1 milligram = 1000 micrograms

The fundamental relationship between milligrams and micrograms is expressed by the conversion factor: 1 milligram (mg) is equal to 1000 micrograms (µg). This conversion factor serves as the cornerstone for all conversions between these two units.

To delve deeper into this relationship, let's examine the prefixes "milli" and "micro." The prefix "milli" originates from the Latin word "mille," meaning "thousand." Therefore, 1 milligram represents one thousandth of a gram (1 mg = 1/1000 g). Similarly, the prefix "micro" stems from the Greek word "mikros," meaning "small." Accordingly, 1 microgram represents one millionth of a gram (1 µg = 1/1,000,000 g).

With a clear understanding of these prefixes and their corresponding values, we can now comprehend the conversion factor of 1 mg = 1000 µg. This conversion factor essentially means that there are 1000 micrograms in every milligram.

To illustrate this conversion, let's consider an example. Suppose you have a bottle of medicine that contains 500 milligrams of a particular ingredient. To determine the amount of this ingredient in micrograms, we can use the conversion factor as follows:

Therefore, there are 500,000 micrograms of the ingredient in the bottle.
