What is the value of 2.5 g when converted to mg?

To convert grams to milligrams, you need to understand the relationship between the two units. One gram is equal to 1,000 milligrams. Therefore, to convert grams to milligrams, you multiply the number of grams by 1,000.

In this case, you have 2.5 grams. To perform the conversion:

2.5 g × 1,000 mg/g = 2,500 mg.

This calculation shows that 2.5 grams is equivalent to 2,500 milligrams, making the answer accurate. It's important to note that there are two acceptable ways to represent the numerical value of milligrams—using a comma or not. However, both "2,500 mg" and "2500 mg" denote the same quantity. Therefore, the choice showing 2,500 mg or its alternative representation aligns correctly with the calculation.
