Convert 2 grams to milligrams.

To convert grams to milligrams, it's important to recall the conversion factor: 1 gram is equal to 1,000 milligrams.

When converting 2 grams to milligrams, you would multiply the number of grams by the conversion factor:

2 grams × 1,000 mg/gram = 2,000 mg.

This calculation shows that 2 grams is equivalent to 2,000 milligrams. Therefore, the correct answer is 2000 mg.

Understanding this conversion is crucial in medication math, as precise dosing is often required in milligrams for medications, while measurements may be given in grams for other substances.
