How to convert

1 pennyweight (dwt) = 1.55517E-06 tonne (tonne). Pennyweight (dwt) is a unit of Weight used in Standard system. Tonne (tonne) is a unit of Weight used in Metric 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 = 1.5552 g
  • 1 dwt = 1555.1738 mg
  • 1 dwt = 0.05 oz t

  • 1 dwt = 24 gr

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

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

  • To convert tonnes to avoirdupois pounds, multiply by 2204.6226. For example, 10 t = 10 x 2204.6226 = 22046.226 lb.
  • To convert tonnes to short tons, multiply by 1.1023. For example, 5 t = 5 x 1.1023 = 5.5115 st.
  • To convert tonnes to long tons, multiply by 0.9842. For example, 20 t = 20 x 0.9842 = 19.684 lt.
  • To convert tonnes to kilograms, multiply by 1000. For example, 15 t = 15 x 1000 = 15000 kg.
  • To convert tonnes to grams, multiply by 1000000. For example, 25 t = 25 x 1000000 = 25000000 g.
  • To convert tonnes to milligrams, multiply by 1000000000. For example, 30 t = 30 x 1000000000 = 30000000000 mg.

  • In the United Kingdom, tonnes are sometimes used for measuring weight, especially for international trade and commerce.
  • In India, tonnes are sometimes used for measuring weight, especially for international trade and commerce.

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.

Example Conversions of Tonnes to Other Units

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

  • 1 t = 2204.6226 lb
  • 1 t = 1.1023 st
  • 1 t = 0.9842 lt
  • 1 t = 1000 kg
