How many milligrams are in a gram?

A gram is a unit of mass commonly used in the metric system. In the metric system, the prefix "milli-" denotes a factor of one thousandth (1/1000). Therefore, when converting grams to milligrams, you multiply the number of grams by 1000.

Since 1 gram is equivalent to 1000 milligrams, choosing the option that states 1000 mg reflects an accurate understanding of metric conversions, particularly relevant in fields like healthcare and medication administration. This knowledge is essential for medication aides, who must accurately measure dosages of various medications to ensure patient safety and effectiveness of treatment.

The other options represent incorrect conversions, as they do not accurately reflect the relationship between grams and milligrams. Understanding this basic conversion is crucial for anyone involved in medication management.
