Troy Pound (lb t) is a unit of Weight used in Standard system.
Milligram (mg) is a unit of Weight used in Metric system. 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 seventhousandth 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.
Where Troy Pounds are Used
Troy pounds are used in different countries and regions for different applications and purposes. Here are some examples of where troy pounds are used:
 In most countries that use the SI system, troy pounds are not used for measuring weight, but only for measuring precious metals, such as gold, silver and platinum.
 In the United States, troy pounds are used for measuring precious metals, especially for gold and silver coins and bullion.
 In Canada, Australia and New Zealand, troy pounds are used for measuring precious metals, especially for gold and silver coins and bullion.
 In the United Kingdom, troy pounds are used for measuring precious metals, especially for gold and silver coins and bullion.
 In India, troy pounds are used for measuring precious metals, especially for gold and silver jewelry.
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.

Milligrams: A Unit of Weight
Milligrams are a unit of weight that are used in the International System of Units (SI), also known as the metric system. Milligrams are derived from the Latin word mille, which means thousand, and the French word gramme, which means weight. The symbol for milligram is mg.
Definition of the Milligram
The milligram is defined as one onethousandth of a gram, which is one onemillionth of a kilogram, which is the base unit of mass in the SI. The kilogram is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015 ×10 −34 when expressed in the unit J s, which is equal to kg m 2 s −1, where the meter and the second are defined in terms of c and ∆ν Cs. The Planck constant is a fundamental physical constant that relates the energy of a photon to its frequency.
The milligram is a very small unit of weight, equivalent to about 0.000035 ounces or 0.000002 pounds. It is commonly used for measuring small masses, such as medicines, chemicals, vitamins, minerals and microorganisms.
How to Convert Milligrams
Milligrams can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert milligrams to other units of weight in the US customary system and the SI system:
 To convert milligrams to ounces, divide by 28349.523125. For example, 1000 mg = 1000 / 28349.523125 = 0.035 oz.
 To convert milligrams to pounds, divide by 453592.37. For example, 5000 mg = 5000 / 453592.37 = 0.011 lb.
 To convert milligrams to tons (short), divide by 907184740. For example, 10000 mg = 10000 / 907184740 = 0.000011 ton.
 To convert milligrams to grams, divide by 1000. For example, 2000 mg = 2000 / 1000 = 2 g.
 To convert milligrams to kilograms, divide by 1000000. For example, 3000 mg = 3000 / 1000000 = 0.003 kg.
 To convert milligrams to micrograms, multiply by 1000. For example, 50 mg = 50 x 1000 = 50000 µg.

History of Milligrams
Milligrams have a long history that dates back to ancient times. Here are some highlights of the history of milligrams:
 The milligram was originally based on the weight of a grain of wheat or barley, which was used as a unit of mass in ancient civilizations such as Egypt, Mesopotamia and Greece.
 The milligram was part of the gramcentimetersecond system of units (CGS) that was developed in the 19th century as an alternative to the meterkilogramsecond system of units (MKS).
 The milligram was replaced by the kilogram as the base unit of mass in the SI system that was adopted in 1960 as an international standard for measurements.
 The milligram was redefined in terms of the kilogram and the Planck constant in 2019 as part of a major revision of the SI system.
