Troy Pounds: A Unit of Weight

Troy pounds are a unit of weight that are used for measuring precious metals, such as gold, silver and platinum. Troy pounds are derived from the French word troye, which was the name of a market town in France where English merchants traded in the Middle Ages. The symbol for troy pound is lb t.

Definition of the Troy Pound

The troy pound is defined as 12 troy ounces, which are each 20 pennyweights, which are each 24 grains. The troy grain is equal to the avoirdupois grain, which is one seven-thousandth of an avoirdupois pound. The troy ounce is heavier than the avoirdupois ounce, but the troy pound is lighter than the avoirdupois pound.

The troy pound is equal to about 0.8229 avoirdupois pounds or 0.3732 kilograms. The troy ounce is equal to about 1.0971 avoirdupois ounces or 31.1035 grams. The troy grain is equal to about 0.0648 milligrams.

How to Convert Troy Pounds

Troy pounds can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert troy pounds to other units of weight in the US customary system and the SI system:

• To convert troy pounds to avoirdupois pounds, multiply by 0.8229. For example, 10 lb t = 10 x 0.8229 = 8.229 lb.
• To convert troy pounds to avoirdupois ounces, multiply by 13.1657. For example, 5 lb t = 5 x 13.1657 = 65.8285 oz.
• To convert troy pounds to tons (short), divide by 1216.05. For example, 20 lb t = 20 / 1216.05 = 0.0164 ton.
• To convert troy pounds to kilograms, multiply by 0.3732. For example, 15 lb t = 15 x 0.3732 = 5.598 kg.
• To convert troy pounds to grams, multiply by 373.2417. For example, 25 lb t = 25 x 373.2417 = 9331.0425 g.
• To convert troy pounds to milligrams, multiply by 373241.7216. For example, 30 lb t = 30 x 373241.7216 = 11197251.648 mg.

History of Troy Pounds

Troy pounds have a long history that dates back to ancient times. Here are some highlights of the history of troy pounds:

• The troy pound was originally based on the weight of a Roman libra, which was a unit of mass used in ancient Rome that was equivalent to about 328 grams.
• The troy pound was used in different systems of measurement, such as the Roman system, the Byzantine system, the Arabic system and the English system. It varied from about 350 grams to about 400 grams depending on the region and the time period.
• The troy pound was standardized by royal statutes and international agreements in different periods of history. For example, in 1527 an act of Henry VIII fixed the troy pound at exactly 5760 grains; in 1828 an act of Congress adopted the troy pound as the official unit of weight for coinage in the United States; in 1959 an international agreement defined the international avoirdupois ounce as exactly 28.349523125 grams, which made the troy ounce exactly 31.1034768 grams.

Tonnes: A Unit of Weight

Tonnes are a unit of weight that are used for measuring large masses, such as vehicles, ships, and buildings. Tonnes are also known as metric tons or megagrams. The symbol for tonne is t.

Definition of the Tonne

The tonne is defined as 1000 kilograms, which is the base unit of mass in the International System of Units (SI). The tonne is also equal to one million grams or one billion milligrams.

The tonne is equal to about 2204.6 avoirdupois pounds or 1.1023 short tons. The tonne is also equal to about 0.9842 long tons or 0.9072 tonnes-force.

How to Convert Tonnes

History of Tonnes

Tonnes have a relatively short history that dates back to the late 18th century. Here are some highlights of the history of tonnes:

• The tonne was originally based on the weight of a cubic meter of water at its maximum density of four degrees Celsius, which was approximately equal to 1000 kilograms.
• The tonne was part of the original metric system that was introduced in France in 1795 as a decimal-based system of measurement that was designed to replace the traditional units that varied from region to region.
• The tonne was adopted by many countries around the world as part of the International System of Units (SI) that was established in 1960 as a universal system of measurement that was based on seven base units and several derived units.
• The tonne was also referred to as the metric ton or the megagram in some countries and contexts to distinguish it from the non-metric units of the short ton and the long ton.
