## Units

### Ounce (oz)

An imperial and US customary unit of mass equal to approximately 28.35 grams. Commonly used in the US and UK for food and postal weight.

### Troy Pound (lb t)

A troy pound equals 12 troy ounces or 5,760 grains (373.2417216 grams). It is lighter than the avoirdupois pound and is rarely used today outside of historical contexts.

## Background

The troy pound was historically used in minting coins, and many nations defined their currency's silver or gold content in troy pounds. The British Royal Mint weighed gold and silver in troy pounds for centuries. While the troy ounce remains in active use for precious metals pricing, the troy pound has become largely obsolete, replaced by the troy ounce as the preferred unit for modern bullion trading.

## Good to Know

The troy pound's role in minting gave it outsized historical importance. When the English pound sterling was first defined in the 12th century, it was literally one troy pound of sterling silver divided into 240 silver pennies. This direct link between weight and currency persisted for centuries and explains why the British monetary unit shares its name with a unit of weight.

## FAQ

### How many avoirdupois ounces are in a troy pound?

One troy pound equals approximately 13.166 avoirdupois ounces. The troy pound is 12 troy ounces (373.242 grams), which converts to about 13.166 avoirdupois ounces since avoirdupois ounces are lighter than troy ounces.

### Why is a troy pound lighter than an avoirdupois pound?

A troy pound has only 12 troy ounces (373.24 g) versus 16 avoirdupois ounces (453.59 g) in an avoirdupois pound. Even though each troy ounce is individually heavier than each avoirdupois ounce, having four fewer ounces per pound makes the troy pound about 17.5 percent lighter overall.

### Is the troy pound still used?

The troy pound has largely fallen out of use. Modern precious metals trading uses troy ounces rather than troy pounds. The troy pound's primary relevance today is historical, appearing in old mint records, coin collecting references, and legal definitions of certain currency standards that have since been replaced.

## Non-Frequently Asked Questions

### If a troy pound has 12 ounces instead of 16, is it on a diet?

The troy pound has always had 12 ounces. It did not slim down; it was born smaller. The avoirdupois pound later showed up with 16 ounces and became the standard for general commerce, making the troy pound look undersized by comparison. It is not a diet; it is a different ancestry.

### If I say I have a pound of gold, which pound do I mean?

In the precious metals world, a 'pound of gold' should mean a troy pound (12 troy ounces, 373.24 grams). However, most people outside the industry would assume you mean an avoirdupois pound (453.59 grams). The ambiguity has caused genuine confusion in transactions, which is why professionals always specify 'troy ounces' and avoid the word 'pound' entirely.

### Is 'a pound of gold versus a pound of feathers' even harder with troy pounds?

It becomes a genuine trick question. A troy pound of gold (373.24 g) is actually lighter than an avoirdupois pound of feathers (453.59 g). So if someone asks which weighs more, a pound of gold or a pound of feathers, the technically correct answer depends on which pound system each is using. The feathers win if the gold is troy and the feathers are avoirdupois.
