Grams in a Troy Ounce: A Comprehensive Guide

Understanding the Troy Ounce

The troy ounce (oz t) is a unit of mass commonly used in the precious metals trade. It is distinct from the avoirdupois ounce (oz), which is commonly used for measuring weight in everyday situations. The troy ounce is 31.1034768 grams, which is slightly heavier than the avoirdupois ounce (28.3495231 grams).

Converting Grams to Troy Ounces

To convert grams to troy ounces, divide the weight in grams by 31.1034768. For example, 100 grams is equal to 100 ÷ 31.1034768 = 3.21507465 troy ounces.

Converting Troy Ounces to Grams

To convert troy ounces to grams, multiply the weight in troy ounces by 31.1034768. For example, 5 troy ounces is equal to 5 × 31.1034768 = 155.517384 grams.
