How many milligrams are in five grams?

To determine how many milligrams are in five grams, it's important to remember the conversion factors between grams and milligrams. One gram is equivalent to 1,000 milligrams. Therefore, to convert grams to milligrams, you multiply the number of grams by 1,000.

In this case, you have five grams. So the calculation would be:

5 grams × 1,000 mg/gram = 5,000 mg.

This shows that five grams is equal to 5,000 milligrams, which is why this answer is the correct choice. Understanding this basic unit conversion is crucial in many health science applications, where precise measurements of mass can significantly impact outcomes.
