Understand the relationship between grams and milligrams: 1 gram (g) is equal to 1000 milligrams (mg).
Set up the conversion using the given value: multiply 0.8 grams by the conversion factor 1000 mg / 1 g.
Write the conversion expression as: \(0.8 \text{ g} \times \frac{1000 \text{ mg}}{1 \text{ g}}\).
Cancel the units of grams to leave the result in milligrams: grams cancel out, leaving milligrams.
Multiply the numbers: \(0.8 \times 1000\) to find the equivalent value in milligrams.
