Grams vs troy ounces: what is the difference?
Gram (g)
A gram is a metric unit of mass. It is used globally in science, retail, and day-to-day measurement. It is straightforward and decimal-based.
Troy ounce (ozt)
A troy ounce is a traditional unit used for precious metals. It is not the same as the common ounce used in grocery and household measurements.
- 1 troy ounce = 31.1034768 grams
- 1 regular (avoirdupois) ounce = 28.349523125 grams
Because these are different systems, mixing them up can cause costly misunderstandings.

Buying bullion bars and coins

For precious metal investors, consistent units make portfolio reporting cleaner and easier to analyze over time.
Tips for better accuracy

- Keep unit systems consistent across all calculations.
- Round only at the final step, not in the middle of a multi-step valuation.
- Double-check whether a listing says “oz” or “ozt”.
