Quick estimate in your head
For a rough answer, multiply by about 0.005: 250 × 0.005 ≈ 1.25 ct, against the exact 1.25 ct (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 milligram is smaller than a carat, so the number of carats must come out smaller than the number of milligrams. If your answer goes the other way, divide instead of multiplying.
