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.
• To convert grains to tons (short), divide by 14000000. For example, 20 gr = 20 / 14000000 = 0.0000014 ton.
• To convert grains to kilograms, divide by 15432.3584. For example, 15 gr = 15 / 15432.3584 = 0.000972 kg.
• To convert grains to grams, divide by 15.4323584. For example, 25 gr = 25 / 15.4323584 = 1.6218 g.
• To convert grains to milligrams, multiply by 64.79891. For example, 30 gr = 30 x 64.79891 = 1943.9673 mg.

Where Grains are Used

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

• In most countries that use the SI system, grains are not used for measuring weight, but only for measuring small masses, such as bullets, arrows, and seeds.
• In the United States, grains are sometimes used for measuring small masses, such as bullets, arrows, and seeds.
• In Canada, Australia and New Zealand, grains are sometimes used for measuring small masses, such as bullets, arrows, and seeds.
• In the United Kingdom, grains are sometimes used for measuring small masses, such as bullets, arrows, and seeds.
• In India, grains are sometimes used for measuring small masses, such as bullets, arrows, and seeds.

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.
• The grain was part of different systems of measurement, such as the Tower system, the Troy system, the Avoirdupois system and the Apothecaries’ system. It varied from about 40 milligrams to about 80 milligrams depending on the region and the time period.
• The grain was standardized by royal statutes and international agreements in different periods of history. For example, in 1527 an act of Henry VIII fixed the grain at exactly one seven-thousandth of an avoirdupois pound; 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.

Example Conversions of Grains to Other Units

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

• 1 gr = 0.0023 oz
• 1 gr = 0.0001 lb
• 1 gr = 0.00000007 ton

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.

Where Tonnes are Used

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

• In most countries that use the SI system, tonnes are used for measuring weight, especially for large masses, such as vehicles, ships, and buildings.
• In the United States, tonnes are sometimes used for measuring weight, especially for international trade and commerce.

• 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.
