Gallons: A Unit of Volume

Gallons are a unit of volume that are used to measure liquids, such as water, milk, oil, wine, etc. They are also used to measure some dry goods, such as grains, fruits, nuts, etc. They are different from cups, which are a smaller unit of volume. They are also different from liters, which are a larger unit of volume. They are also different from barrel of oil equivalent (BOE), which is a unit of energy based on the approximate energy released by burning one barrel of crude oil.

Definition of Gallons

A gallon is defined as a unit of liquid capacity in both the US customary and imperial systems of measurement. However, the size of a gallon varies depending on the type of gallon used:

• A US liquid gallon is equal to 3.785 liters or 0.833 UK gallons in the metric system. It is equivalent to 231 cubic inches or 128 fluid ounces in the US customary system.
• A US dry gallon is equal to 4.405 liters or 0.969 UK gallons in the metric system. It is equivalent to 268.8 cubic inches or 148.9 fluid ounces in the US customary system.
• A UK gallon is equal to 4.546 liters or 1.2 US liquid gallons in the metric system. It is equivalent to 277.4 cubic inches or 160 fluid ounces in the imperial system.

History of Gallons

The origin of the term gallon as a unit of measure is uncertain, but it may have derived from the Old French word galon, which means a large liquid measure. Gallons have been used since ancient times to store and transport various liquids and dry goods. The size and shape of gallons varied depending on the type and quantity of the goods, the availability of materials, and the customs of different regions and countries.

The use of gallons as a unit of measure dates back to the medieval times, when the European system of measurement was established. The standard size of these gallons was based on the wine gallon, which was originally defined as the volume of eight pounds of wine at 62 °F. The gallon was convenient for measuring and dividing larger amounts of liquids and dry goods.

The use of gallons as a unit of measure continued until the 20th century, when the metric system of measurement was adopted in most countries. The gallon was gradually replaced by units such as liters, kilograms, etc. However, some countries and regions still use gallons for certain types of liquids and dry goods, especially in the United States and the United Kingdom and its former colonies.

Where Gallons are Used

Gallons are mainly used in some countries and regions that use the US customary system or the imperial system of measurement. They are often used for measuring and adding liquids such as water, milk, oil, wine, etc., and dry goods such as grains, fruits, nuts, etc., to recipes.

In some countries that use the metric system of measurement, such as Canada and Australia, gallons are not commonly used or recognized. Instead, they use units such as liters, kilograms, etc.

Hectoliters: A Unit of Volume

Definition of the Hectoliter

A hectoliter is a unit of volume that measures how much space an object or substance occupies. It is equal to 100 liters, or 0.1 cubic meters, or 0.0001 cubic kilometers. One hectoliter can also be written as hL or 10⁵ mL.

History of the Hectoliter

The hectoliter is a metric unit that was derived from the liter, which was first defined in 1795 by the French Academy of Sciences as one thousandth of a cubic meter. The liter was later redefined several times based on different physical standards, such as a platinum-iridium cylinder and a krypton-86 atom. In 1964, the liter was finally defined as a name given to the cubic decimeter, or 0.001 cubic meters.

The hectoliter, as well as other metric units of volume, such as the deciliter and the centiliter, were introduced in the 19th century as part of the decimal system of measurement that aimed to simplify and unify the units used in science and commerce. The hectoliter was officially adopted by the International System of Units (SI) in 1960 as one of the seven base units.

How to Convert Hectoliters

To convert hectoliters to other units of volume, we need to use conversion factors that relate the hectoliter to the desired unit. For example, to convert hectoliters to gallons, we need to know that one gallon is equal to 3.785 liters. Therefore, one hectoliter is equal to 100 liters, or 26.418 gallons.

Here are some common conversion factors for hectoliters:

• 1 hL = 100 L
• 1 hL = 26.418 US gallons
• 1 hL = 21.997 UK gallons
• 1 hL = 3.531 ft³
• 1 hL = 0.131 yd³
• 1 hL = 0.167 barrels (oil)
• 1 hL = 0.014 acre-feet

To convert from other units of volume to hectoliters, we need to use the inverse of these conversion factors. For example, to convert gallons to hectoliters, we need to divide by 26.418.

Where Hectoliters are Used

The hectoliter is a unit of volume that is mainly used to measure the volume of liquids such as water, beer, wine and milk. For example, according to Craft Beer & Brewing Magazine, the hectoliter is the major unit of volume used in the brewing industry worldwide1. The annual production of beer in different countries is often reported in hectoliters. According to Wikipedia, the global production of beer in 2019 was about 1.913 billion hectoliters.

The hectoliter is also used to measure the volume of some agricultural products such as grains, fruits and vegetables. For example, according to Statista, the global production of wheat in 2020 was about 765 million hectoliters.

Example Conversions of Hectoliters to Other Units

Here are some examples of how to convert hectoliters to other units of volume using the conversion factors given above:

• 2 hL = 2 x 100 L = 200 L
• 3 hL = 3 x 26.418 US gallons = 79.254 US gallons
• 4 hL = 4 x 21.997 UK gallons = 87.988 UK gallons
• 5 hL = 5 x 3.531 ft³ = 17.655 ft³
• 6 hL = 6 x 0.131 yd³ = 0.786 yd³
• 7 hL = 7 x 0.167 barrels (oil) = 1.169 barrels (oil)
• 8 hL = 8 x 0.014 acre-feet = 0.112 acre-feet

Conclusion

The hectoliter is a unit of volume that is equal to 100 liters, or one tenth of a cubic meter. It is mainly used to measure the volume of liquids such as water, beer, wine and milk, as well as some agricultural products such as grains, fruits and vegetables. To convert hectoliters to other units of volume, we need to use conversion factors that relate the hectoliter to the desired unit.
