Quick estimate in your head

For a rough answer, multiply by about 0.005: 7 × 0.005 ≈ 0.035 ct, against the exact 0.035 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.
