What is the US Hundredweight?
The US hundredweight, also called the short hundredweight or cental, is a unit of mass used in North American commerce and agriculture for bulk commodities such as grain, livestock, and cattle feed.
Definition
The US hundredweight is defined as exactly 100 avoirdupois pounds:
Precisely, 1 US cwt = 100 lb = 45.359237 kg exactly. Twenty US hundredweights make one US (short) ton of 2000 lb.
Origin and History
The hundredweight has medieval English origins, where a "hundred" of weight varied by commodity and region. North American usage settled on a clean 100-pound unit—hence "short"—diverging from the British long hundredweight of 112 pounds.
Law and Notable Facts
In the United States the hundredweight is legally 100 lb and is standard in commodity pricing; agricultural products such as milk, hogs, and grain are still quoted per hundredweight (cwt). The abbreviation "cwt" uses the Roman numeral C for one hundred.
Real-World Examples and Conversions
Milk is often priced per hundredweight; for example, "$20 per cwt" means per 100 lb (≈45.4 kg). Twenty US hundredweights equal one short ton (907.18 kg). One US cwt is lighter than one UK cwt (≈50.80 kg).
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.
