Quick estimate in your head
For a rough answer, multiply by about 200: 80 × 200 ≈ 16,000 mg, against the exact 16,000 mg (0.0% out). Good enough to check that a calculated result is sensible.
Common mistakes
The usual slip is using the factor the wrong way round. A carat is bigger than a milligram, so the number of milligrams must come out larger than the number of carats. If your answer goes the other way, divide instead of multiplying.
