An Introduction to US Short Hundredweights

US short hundredweights are a unit of weight in the US customary system that are equal to 100 pounds. They are also known as centals or simply hundredweights, and are commonly used for measuring the quantities of some agricultural products or industrial materials. In this article, we will explore the definition, history, conversion and usage of US short hundredweights.

Definition of US Short Hundredweights

A US short hundredweight is a unit of weight in the US Customary System equal to 100 pounds (45.36 kilograms). The symbol for US short hundredweight is cwt, and it is derived from the Latin word centum, meaning “hundred”. A US short hundredweight is also equivalent to 45.359237 kilograms, 0.05 US short tons or 0.045359237 metric tons.

History of US Short Hundredweights

US short hundredweights were introduced as a unit of measurement in the US and Canada in the late 18th or early 19th century, as a way to simplify the trading of some goods between countries. They were based on the British imperial system, which defined one hundredweight as 112 pounds. However, since the British hundredweight was too heavy for some purposes, such as measuring grains or livestock, the US and Canada adopted a lighter version of 100 pounds.

The US short hundredweight was also influenced by the French metric system, which was introduced in 1795 and used a base-ten system of units. The French system had a unit of mass called the quintal, which was equal to 100 kilograms or 220.462 pounds. The US short hundredweight was similar to the quintal, but slightly lighter.

The US short hundredweight was officially recognized by the US government in 1836, when it passed a law that defined one bushel of wheat as 60 pounds and one barrel of flour as 196 pounds. These measures were based on the US short hundredweight of 100 pounds.

The use of the US short hundredweight as a measurement has declined in recent years in favor of the metric system or other units such as pounds or tons. However, it is still used for some commodities such as grains, oilseeds, paper, and concrete additives.

How to Convert US Short Hundredweights

US short hundredweights can be easily converted to other units of weight by multiplying or dividing by appropriate factors. For example, to convert US short hundredweights to pounds, we multiply by 100; to convert US short hundredweights to kilograms, we multiply by 45.359237; to convert US short hundredweights to tons, we divide by 20.

Where US Short Hundredweights are Used

US short hundredweights are commonly used for measuring the quantities of some agricultural products or industrial materials in the US and Canada. Here are some examples:

• In agriculture, US short hundredweights are used for measuring the weight of grains such as wheat, corn, oats, barley, rye, and rice; oilseeds such as soybeans, canola, sunflower seeds, and flax seeds; hay and straw; sugar beets; and potatoes.
• In industry, US short hundredweights are used for measuring the weight of paper products such as newsprint, printing paper, tissue paper, and cardboard; concrete additives such as cement and fly ash; and steel products such as bars, rods, plates, and sheets.
• In commerce, US short hundredweights are used for pricing some commodities on futures exchanges such as the Chicago Board of Trade (CBOT) and the Minneapolis Grain Exchange (MGEX). For example, wheat futures contracts are quoted in cents per bushel based on a contract size of 5,000 bushels or 136 metric tons or 3,000 cwt.

Example Conversions of US Short Hundredweights to Other Units

Here are some example conversions of US short hundredweights to other units:

• To convert 2 cwt to lb, we multiply by 100: 2 cwt x 100 = 200 lb
• To convert 5 cwt to kg, we multiply by 45.359237: 5 cwt x 45.359237 = 226.796185 kg
• To convert 3 cwt to t, we divide by 20: 3 cwt / 20 = 0.15 t
• To convert 6 cwt to oz, we multiply by 1600: 6 cwt x 1600 = 9600 oz
• To convert 7 cwt to g, we multiply by 45359.237: 7 cwt x 45359.237 = 317513.659 g

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
