Micrograms: A Unit of Weight

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).

Stones: A Unit of Weight

Stones are a unit of weight that are used in the British imperial system and the US customary system. Stones are derived from the use of stones for weights, a practice that dates back to ancient times. The word stone comes from the Old English stan, meaning stone, and the abbreviation st comes from the Latin word statera, meaning balance.

Definition of the Stone

The stone is defined as 14 pounds avoirdupois, which is equal to 6.35 kilograms or 224 ounces. The avoirdupois pound is defined as 7000 grains, which is a unit of mass based on the weight of a grain of wheat. The stone is one-eighth of a hundredweight, which is 112 pounds, and one-quarter of a quarter, which is 28 pounds.

The stone is not a legal unit of measurement in most countries, except for the United Kingdom and Ireland, where it is still used for measuring body weight. In other countries, such as the United States, Canada, Australia and New Zealand, the stone is sometimes used informally for expressing human weight.

How to Convert Stones

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

  • To convert stones to pounds, multiply by 14. For example, 10 st = 10 x 14 = 140 lb.
  • To convert stones to ounces, multiply by 224. For example, 5 st = 5 x 224 = 1120 oz.
  • To convert stones to tons (short), divide by 142.857. For example, 20 st = 20 / 142.857 = 0.14 ton.
  • To convert stones to kilograms, multiply by 6.35. For example, 8 st = 8 x 6.35 = 50.8 kg.
  • To convert stones to grams, multiply by 6350. For example, 3 st = 3 x 6350 = 19050 g.
  • To convert stones to milligrams, multiply by 6350000. For example, 2 st = 2 x 6350000 = 12700000 mg.

Where Stones are Used

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

  • In the United Kingdom and Ireland, stones are used for measuring body weight and livestock weight. For example, a person may weigh 11 st or a cow may weigh 40 st.
  • In the United States, stones are sometimes used for measuring body weight and sports equipment. For example, a boxer may weigh 12 st or a bowling ball may weigh 1 st.
  • In Canada, Australia and New Zealand, stones are sometimes used for measuring body weight and agricultural products. For example, a person may weigh 9 st or a bag of potatoes may weigh 2 st.
  • In some African countries, such as Kenya and Uganda, stones are sometimes used for measuring crops and commodities. For example, a sack of maize may weigh 4 st or a bunch of bananas may weigh 1 st.

History of Stones

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

  • The stone was an ancient unit of measurement that was based on the weight of a natural stone or rock. It varied from place to place and from time to time depending on the type and size of the stone used.
  • The stone was used in different systems of measurement, such as the Roman system, the Anglo-Saxon system, the English system and the Scottish system. It ranged from about 5 pounds to about 40 pounds depending on the region and the object weighed.
  • The stone was standardized by royal statutes and international agreements in different periods of history. For example, in 1389 a royal statute fixed the stone of wool at 14 pounds in England; in 1824 an international agreement defined the avoirdupois pound as exactly 453.59237 grams; in 1835 an act permitted using a stone of 14 pounds for trade in Britain; in 1959 an international agreement defined the international avoirdupois ounce as exactly 28.349523125 grams.
