How to convert

1 pennyweight (dwt) = 24 grain (gr). Pennyweight (dwt) is a unit of Weight used in Standard system. Grain (gr) is a unit of Weight used in Standard system.

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

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

  • In most countries that use the SI system, pennyweights are not used for measuring weight, but only for measuring precious metals, such as gold, silver and platinum.
  • In the United States, pennyweights are sometimes used for measuring precious metals, especially for gold and silver jewelry and scrap.
  • In Canada, Australia and New Zealand, pennyweights are sometimes used for measuring precious metals, especially for gold and silver jewelry and scrap.
  • In the United Kingdom, pennyweights are sometimes used for measuring precious metals, especially for gold and silver jewelry and scrap.
  • 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.

Example Conversions of Pennyweights to Other Units

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

  • 1 dwt = 0.0549 oz
  • 1 dwt = 0.0034 lb
  • 1 dwt = 0.0000017 ton
  • 1 dwt = 0.0016 kg

  • 1 dwt = 0.0833 lb t
  • 1 dwt = 24 gr

Grains: A Unit of Weight

Grains are a unit of weight that are used for measuring small masses, such as bullets, arrows, and seeds. Grains are derived from the English word grain, which was the name of a seed or a cereal plant. The symbol for grain is gr.

Definition of the Grain

The grain is defined as one seven-thousandth of an avoirdupois pound, which is the common unit of weight in the US customary system and the British imperial system. The grain is equal to the troy grain, which is the smallest unit of the troy weight system, which is used for measuring precious metals. The grain is also equal to the apothecaries’ grain, which is the smallest unit of the apothecaries’ weight system, which is used for measuring medicines.

The grain is equal to about 0.0023 avoirdupois ounces or 0.0648 grams. The grain is also equal to about 0.00014 troy ounces or 0.0417 pennyweights.

How to Convert Grains

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

  • To convert grains to avoirdupois ounces, divide by 437.5. For example, 10 gr = 10 / 437.5 = 0.0229 oz.
  • To convert grains to avoirdupois pounds, divide by 7000. For example, 5 gr = 5 / 7000 = 0.0007 lb.

History of Grains

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

  • The grain was originally based on the weight of a single seed of wheat or barley, which was used as a unit of mass in ancient civilizations such as Egypt, Mesopotamia and Greece.
