Quick Tips
- Remember: 5 carats = 1 gram, because 1 carat = 0.2 g.
- Also: 1 pound ≈ 2,268 carats, so pounds are much larger.
- For fast estimates, use 1 carat ≈ 0.000441 lb.
- Do not round early when converting large parcels, round at the final step.
- If you convert through grams, use: carats → grams (×0.2), then grams → pounds (÷453.59237).
- When results are very small, keep at least 6 decimal places in pounds to avoid losing detail.
