Quick answer
What this calculator tells you
Pawn shops and jewelry buyers often quote gold in pennyweights (DWT) because the unit sounds small. Convert their DWT figure back to grams and troy ounces so you can compare offers against the spot price.
Formula
Pennyweight (DWT) to Grams Converter formula
Grams = pennyweights x 1.55517384. There are 20 DWT in a troy ounce.
Use cases
When to use it
- Translate a pawn shop's per-DWT offer into a per-gram price you can compare.
- Convert an old jewelry appraisal listed in DWT into grams.
- Check that a buyer's DWT weight matches your gram scale reading.
Limits
What to check before relying on the number
- A per-DWT price sounds lower than the same per-gram price — always convert before comparing offers.
- Some buyers round DWT down; weigh items yourself in grams first.
- DWT is weight only; purity (karat) still multiplies the value.

Why do pawn shops use pennyweights?
