Troy Weight Conversion Calculator

A Troy Weight Conversion Calculator is an online tool used to convert measurements within the troy weight system and between troy weight and standard avoirdupois weight units. The troy system is commonly used for measuring precious metals such as gold, silver, platinum, and palladium.

Because troy weights differ from everyday weight measurements, using a reliable conversion calculator helps avoid costly mistakes when buying, selling, or valuing precious metals.

What Is the Troy Weight System?

The troy weight system is a traditional unit of mass that dates back to medieval Europe and is still widely used in the precious metals industry today. Unlike the standard (avoirdupois) system used for common goods, troy weight has different unit sizes and conversion values.

The most important distinction is that a troy ounce is heavier than a standard ounce, even though a troy pound contains fewer ounces.

Troy Weight Units Explained

Troy Grain (gr)

The grain is the smallest unit of troy weight. It is the same size in both the troy and avoirdupois systems.

Troy Pennyweight (dwt)

One pennyweight equals 24 grains. Pennyweights are often used in jewelry and gemstone measurements.

Troy Ounce (oz t)

One troy ounce equals 20 pennyweights or 480 grains. This is the standard unit used to price precious metals.

Troy Pound (lb t)

One troy pound equals 12 troy ounces or 5,760 grains.

1 troy pound = 5,760 grains

Troy Weight vs Avoirdupois Weight

Understanding the difference between troy weight and avoirdupois weight is critical.

A troy ounce weighs approximately 31.1035 grams
A standard (avoirdupois) ounce weighs approximately 28.3495 grams

A troy pound weighs approximately 373.24 grams
A standard pound weighs approximately 453.59 grams

This difference means that confusing the two systems can lead to incorrect pricing or valuation.
