Converting the other way: carats to grams

grams = carats × 0.2. So 100 carats is back to 20 grams; one carat is 0.2 grams. See the carats to grams table.

Quick estimate in your head

For a rough answer, multiply by about 5: 20 × 5 ≈ 100 ct, against the exact 100 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 gram is bigger than a carat, so the number of carats must come out larger than the number of grams. If your answer goes the other way, divide instead of multiplying.
