What is the Troy Ounce?
The troy ounce is a unit of mass used almost exclusively for precious metals such as gold, silver, platinum, and palladium. It is the standard weight quoted on global bullion markets.
Definition
The troy ounce is defined as exactly 480 grains, which equals 31.1034768 grams:
By definition, 1 troy ounce = 480 grains = 31.1034768 g exactly, and 12 troy ounces make one troy pound (≈373.242 g). Note that the troy ounce is heavier than the more familiar avoirdupois ounce (≈28.3495 g).
Origin and History
The troy system takes its name from the French market town of Troyes, a major medieval trading hub. It descends from the Roman monetary system and was standardized in England for coinage and precious metals, later adopted across Europe and the English-speaking world.
Law and Notable Facts
The troy ounce remains the legal basis for bullion trading and coinage weights; in the United States it is codified for precious-metal transactions. A curious consequence is that a pound of gold (troy, ~373 g) actually weighs less than a pound of feathers (avoirdupois, ~454 g).
Real-World Examples and Conversions
A standard Good Delivery gold bar weighs about 400 troy ounces (≈12.4 kg). A 1 oz American Gold Eagle contains one troy ounce (31.1 g) of gold. When gold is quoted at "$2,000 per ounce," that means per troy ounce, not the avoirdupois ounce.
What is the UK Hundredweight?
The UK hundredweight, also called the long hundredweight, is a British imperial unit of mass historically used for coal, agricultural produce, and other bulk goods.
Definition
The UK hundredweight is defined as exactly 112 avoirdupois pounds:
Precisely, 1 UK cwt = 112 lb = 8 stone = 50.80234544 kg exactly. Twenty long hundredweights make one long (imperial) ton of 2240 lb.
Origin and History
The value of 112 pounds arose so that the hundredweight would divide evenly into quarters of 28 lb and into stones of 14 lb, easing trade calculations. This "long" hundredweight became standard in Britain and the Commonwealth, in contrast to the North American 100-pound "short" hundredweight.
Law and Notable Facts
Under the British imperial system the hundredweight is legally 112 lb. Its neat divisibility into 4 quarters, 8 stone, or 16 pieces of 7 lb made it convenient before decimalization; it remains recognized for certain traditional trades.
Real-World Examples and Conversions
A traditional bag of coal was often one hundredweight (112 lb, ≈50.8 kg). Twenty UK hundredweights equal one long ton (1016.05 kg). The UK cwt is about 12% heavier than the US cwt of 100 lb (≈45.36 kg).
