Quick estimate in your head
For a rough answer, multiply by about 0.0002: 1,000 × 0.0002 ≈ 0.2 kg, against the exact 0.2 kg (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 smaller than a kilogram, so the number of kilograms must come out smaller than the number of carats. If your answer goes the other way, divide instead of multiplying.
