A pennyweight, written dwt, equals 1.55517384 grams. Twenty pennyweights equal one troy ounce. The unit does not change the gold's value; it only changes how the weight is written.

Use the gold-bearing weight, not the full weight when a piece includes stones, a watch movement, steel springs, weighted sections, or other non-gold material. A karat stamp supports the description but does not prove the metal is genuine or solid throughout.

Questions about gold pennyweight.

How much is one dwt of 14K gold worth?

At the reference shown above, one pennyweight of solid 14K gold contains about 0.9072 grams of pure gold and has an estimated melt value of $118.85. Subtract stones and other non-14K parts first.

Is pennyweight better than grams?

No. Either unit gives the same result when converted correctly. One dwt is 1.55517384 grams. Use the unit shown on the scale and do not treat a regular ounce as a troy ounce.

Is melt value the same as a cash offer?

No. Melt value estimates the gold contained in the item. Testing, refining, shipping, fees, and the buyer's margin can reduce an offer.

How do I compare a gold lot with melt value?

Calculate each karat separately, add every buying cost, and divide the full cost by the combined melt estimate. Use the mixed-karat calculator when a lot contains more than one purity.
