A Pennyweight (abbreviated as dwt) is a unit of mass in the traditional Troy weight system, representing exactly 1.555 grams or 1/20th of a Troy Ounce. While much of the world has moved to the metric system, the pennyweight remains the "gold standard" for jewelers and refiners across the Greater Toronto Area (GTA). At 401Gold, we combine this traditional measurement with modern "Trust Through Transparency" to ensure you understand every decimal point of your appraisal.
The Technical Breakdown: Pennyweight vs. Grams vs. Troy Ounces
Understanding the math behind your gold’s value is the best way to avoid being lowballed. Most household scales measure in "avoirdupois" ounces (standard grocery weight), but precious metals are measured in Troy weight.
The Conversion Matrix:
To help you calculate your items' worth before visiting our GTA office, use these standard conversions:
- 1 Pennyweight (dwt) = 1.555 Grams
- 1 Troy Ounce = 20 Pennyweights (dwt)
- 1 Troy Ounce = 31.103 Grams
- 24 Grains = 1 Pennyweight
Expert Tip: If a buyer only gives you a price per gram but weighs your gold in pennyweights, use the formula Weight times 1.555 to ensure the math stays honest. At 401Gold, we provide a digital readout in the unit of your choice to maintain total clarity.

Why Does the "Pennyweight" Still Exist?
It may seem antiquated, but the pennyweight persists because of its perfect mathematical relationship with the Troy Ounce. In the jewelry trade, most "casting grains" and solders are sold in pennyweights.
For residents in the GTA looking to sell gold, the pennyweight is often used for:
- Dental Gold: Crowns and bridges are historically measured in dwt.
- Vintage Jewelry: Pieces from the Edwardian or Victorian eras were often cataloged using this system.
- Scrap Gold Batches: High-volume sellers often prefer the 20-unit-per-ounce simplicity of the pennyweight over the 31.1-unit complexity of grams.
How Can You Be Sure You’re Getting the Best Price in Toronto?
The most common pain point for sellers in the GTA is the fear of a "hidden spread." Some buyers use the confusion between grams and pennyweights to offer a lower price.
