How to convert

1 milligram (mg) = 3.21507E-05 troy ounce (oz t). Milligram (mg) is a unit of Weight used in Metric system. Troy Ounce (oz t) is a unit of Weight used in Standard system.

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 one-thousandth of a gram, which is one one-millionth 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.

Where Milligrams are Used

Milligrams are used in different countries and regions for different applications and purposes. Here are some examples of where milligrams are used:

  • In most countries that use the SI system, milligrams are used for measuring small masses, such as medicines, chemicals, vitamins, minerals and microorganisms.
  • In the United States, milligrams are sometimes used for measuring small masses, such as medicines, chemicals, vitamins, minerals and microorganisms.
  • In Canada, milligrams are used for measuring small masses, such as medicines, chemicals, vitamins, minerals and microorganisms.
  • In Australia and New Zealand, milligrams are used for measuring small masses, such as medicines, chemicals, vitamins, minerals and microorganisms.
  • In China, milligrams are used for measuring small masses, such as medicines, chemicals, vitamins, minerals and microorganisms.

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 gram-centimeter-second system of units (CGS) that was developed in the 19th century as an alternative to the meter-kilogram-second 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.

Example Conversions of Milligrams to Other Units

Here are some examples of conversions of milligrams to other units of weight:

  • 1 mg = 0.000035 oz
  • 1 mg = 0.000002 lb
  • 1 mg = 0.0000000011 ton
  • 1 mg = 0.001 g
  • 1 mg = 0.000001 kg
  • 1 mg = 1000 µg
  • 1 mg = 0.000032 troy oz
  • 1 mg = 0.000032 apothecaries’ oz
  • 1 mg = 0.000035 Spanish oz
  • 1 mg = 0.000034 French oz
Milligrams also can be marked as Milligrammes (alternative British English spelling in UK).

Troy Ounces: A Unit of Weight

Troy ounces are a unit of weight that are used for measuring precious metals, such as gold, silver and platinum. Troy ounces are derived from the French word once, which was the name of a unit of weight used in the Middle Ages. The symbol for troy ounce is oz t.

Definition of the Troy Ounce

The troy ounce is defined as 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 lighter than the apothecaries’ ounce.

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 Ounces

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

  • To convert troy ounces to avoirdupois ounces, multiply by 1.0971. For example, 10 oz t = 10 x 1.0971 = 10.971 oz.
  • To convert troy ounces to avoirdupois pounds, divide by 14.5833. For example, 5 oz t = 5 / 14.5833 = 0.343 lb.
  • To convert troy ounces to tons (short), divide by 29166.67. For example, 20 oz t = 20 / 29166.67 = 0.000685 ton.
  • To convert troy ounces to kilograms, divide by 32.1507. For example, 15 oz t = 15 / 32.1507 = 0.4666 kg.
  • To convert troy ounces to grams, multiply by 31.1035. For example, 25 oz t = 25 x 31.1035 = 777.5875 g.
  • To convert troy ounces to milligrams, multiply by 31103.4768. For example, 30 oz t = 30 x 31103.4768 = 933104.304 mg.

Where Troy Ounces are Used

  • In India, troy ounces are used for measuring precious metals, especially for gold and silver jewelry.

History of Troy Ounces

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

  • The troy ounce was originally based on the weight of a Roman uncia, which was one twelfth of a Roman libra or pound, which was equivalent to about 27 grams.
  • The troy ounce 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 26 grams to about 32 grams depending on the region and the time period.
  • The troy ounce 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 ounce at exactly 480 grains; in 1828 an act of Congress adopted the troy ounce 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.
