How to convert

1 milligram (mg) = 0.000643015 pennyweight (dwt). Milligram (mg) is a unit of Weight used in Metric system. Pennyweight (dwt) 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).

Pennyweights: A Unit of Weight

Pennyweights are a unit of weight that are used for measuring precious metals, such as gold, silver and platinum. Pennyweights are derived from the English word penny, which was the name of a coin used in the Middle Ages. The symbol for pennyweight is dwt.

Definition of the Pennyweight

The pennyweight is defined as 24 grains, which are each one seven-thousandth of an avoirdupois pound. The grain is equal to the troy grain, which is the smallest unit of the troy weight system. The pennyweight is one twentieth of a troy ounce and one two-hundred-and-fortieth of a troy pound.

The pennyweight is equal to about 0.0549 avoirdupois ounces or 1.5552 grams. The grain is equal to about 0.0648 milligrams.

How to Convert Pennyweights

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

  • To convert pennyweights to avoirdupois ounces, divide by 18.2292. For example, 10 dwt = 10 / 18.2292 = 0.5486 oz.
  • To convert pennyweights to avoirdupois pounds, divide by 291.6667. For example, 5 dwt = 5 / 291.6667 = 0.0171 lb.
  • To convert pennyweights to tons (short), divide by 583333.33. For example, 20 dwt = 20 / 583333.33 = 0.000034 ton.
  • To convert pennyweights to kilograms, divide by 643.0149. For example, 15 dwt = 15 / 643.0149 = 0.0233 kg.
  • To convert pennyweights to grams, divide by 0.643. For example, 25 dwt = 25 / 0.643 = 38.8798 g.
  • To convert pennyweights to milligrams, multiply by 1555.1738. For example, 30 dwt = 30 x 1555.1738 = 46655.214 mg.

Where Pennyweights are Used

  • In India, pennyweights are sometimes used for measuring precious metals, especially for gold and silver jewelry and scrap.

History of Pennyweights

Pennyweights have a long history that dates back to ancient times. Here are some highlights of the history of pennyweights:

  • The pennyweight was originally based on the weight of an English silver penny, which was one two-hundred-and-fortieth of a Tower pound or one twentieth of a Tower ounce.
  • The pennyweight was used in different systems of measurement, such as the Tower system, the Troy system, the Avoirdupois system and the Apothecaries’ system. It varied from about 1 gram to about 1.7 grams depending on the region and the time period.
  • The pennyweight was standardized by royal statutes and international agreements in different periods of history. For example, in 1527 an act of Henry VIII fixed the pennyweight at exactly 24 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.
