The troy ounce (oz t) is a unit of weight used for precious metals, equal to approximately 31.1034768 grams. The troy ounce is heavier than the avoirdupois ounce (28.3495 grams) used for everyday weight measurements. The troy ounce is the standard unit for measuring gold, silver, platinum, and other precious metals in the jewelry and bullion industries.

Converting troy ounces to other jewelry weight units is essential for understanding precious metal weights and jewelry specifications. One troy ounce equals approximately 31.1034768 grams, 20 pennyweights, 480 grains, or 155.517384 diamond karats. The troy ounce to gram conversion is common for weight measurements, while troy ounce to pennyweight conversions are fundamental for precious metal weights. Whether you're converting troy ounces to grams for weight measurements, troy ounces to pennyweights for precious metals, or using a troy ounce converter for jewelry calculations, troy ounce conversions are fundamental to precious metal weight measurements.

The troy ounce is extensively used in the jewelry and bullion industries for measuring precious metals. Gold, silver, and platinum are typically priced and sold by the troy ounce. The troy ounce's status as the standard unit for precious metals makes it essential for jewelry and bullion transactions, providing a standard unit for measuring precious metal weights.

The grain is a unit of weight used for precious metals and gemstones, equal to approximately 0.06479891 grams. The grain is one of the smallest units used in jewelry and precious metals, providing precision for measuring very small quantities. One grain equals 1/480 of a troy ounce or 0.32399455 diamond karats.

Converting grains to other jewelry weight units is useful for understanding very small precious metal and gemstone weights. One grain equals approximately 0.06479891 grams, 0.00208333 troy ounces, 0.00208333 pennyweights, or 0.32399455 diamond karats. The grain to gram conversion is fundamental for weight measurements, while grain conversions help communicate very small weights. Whether you're converting grains to grams for weight measurements, grains to troy ounces for precious metal weights, or using a grain converter for jewelry calculations, grain conversions are useful for very small jewelry weight measurements.

The grain is used in jewelry and precious metals for measuring very small quantities. The grain's precision makes it useful for expressing tiny weights, though grams and larger units are more commonly used for most jewelry applications.
