## How to convert

1 microgram (mcg) = 3.21507E-08 troy ounce (oz t). Microgram (mcg) is a unit of Weight used in Metric system. Troy Ounce (oz t) is a unit of Weight used in Standard system.

## Definition of Micrograms

A microgram is a unit of mass or weight equal to one-millionth of a gram. It is part of the metric system, which is based on powers of ten. The symbol for microgram is μg according to the International System of Units (SI); the recommended symbol in the United States and United Kingdom when communicating medical information is mcg. One microgram is equivalent to 0.001 milligrams or 0.000000001 kilograms. It is also equal to 0.000015 grains, which is a unit of weight in the imperial system.

## How to Convert Micrograms

To convert micrograms to other units of weight, we need to multiply or divide by the appropriate conversion factor. For example, to convert micrograms to milligrams, we divide by 1000; to convert micrograms to grams, we divide by 1,000,000; and to convert micrograms to kilograms, we divide by 1,000,000,000. Here are some examples of conversion factors for different units of weight:

• 1 microgram = 0.001 milligram
• 1 microgram = 0.000001 gram
• 1 microgram = 0.000000001 kilogram
• 1 microgram = 0.000000035 ounce
• 1 microgram = 0.000000002 pound
• 1 microgram = 0.000015 grain

## Where Micrograms are Used

Micrograms are very commonly used in scientific and medical fields where precision and accuracy are essential. For example, micrograms may be used to measure:

• The mass of tiny objects or substances, such as bacteria, viruses, DNA, hormones or pollutants.
• The dosage of some medications, such as steroids, anticoagulants or chemotherapy drugs.
• The concentration of some nutrients or toxins in food, water or air.

Micrograms may also be used in different countries for different applications. For example, in China, micrograms are used to measure the weight of silk; in India, micrograms are used to measure the weight of spices; and in Switzerland, micrograms are used to measure the weight of gold.

## History of Micrograms

The origin of micrograms can be traced back to the development of the metric system in France in the late 18th century. The metric system was designed to simplify and standardize the measurement of length, area, volume and mass by using decimal units based on the meter and the kilogram. The gram was defined as one-thousandth of a kilogram, and the microgram was defined as one-millionth of a gram.

The metric system was adopted by many countries around the world over the next two centuries, but it also faced some resistance and opposition from those who preferred the traditional units of measurement. In some cases, the metric system was modified or adapted to suit local needs and preferences. For example, in Germany, the metric system was officially adopted in 1872, but some old units such as pfund (pound) and zentner (hundredweight) are still used today.

The International System of Units (SI) was established in 1960 as a modern version of the metric system that is based on seven base units: meter, kilogram, second, ampere, kelvin, mole and candela. The SI also defines several derived units that are combinations of the base units, such as newton, joule and watt. The SI is recognized as the global standard for measurement and is used by most countries and international organizations today.

## Example Conversions of Micrograms to Other Units

Here are some examples of how to convert micrograms to other units of weight using the conversion factors mentioned above:

• 2 micrograms = 0.002 milligrams
• 5 micrograms = 0.000005 grams
• 10 micrograms = 0.00000001 kilograms
• 15 micrograms = 0.00000053 ounces
• 20 micrograms = 0.00000004 pounds
• 25 micrograms = 0.00039 grains
Micrograms also can be marked as Microgrammes or µg (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

Troy ounces are used in different countries and regions for different applications and purposes. Here are some examples of where troy ounces are used:

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