Fluid Ounces: A Unit of Volume

Fluid ounces 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 ounces, which are a unit of weight or mass. 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 Fluid Ounces

A fluid ounce is a unit of volume or capacity in both the imperial and US customary systems of measurement. However, the size of a fluid ounce varies depending on the type of fluid ounce used:

  • A UK fluid ounce is equal to one twentieth of a UK pint in the imperial system of measurement. It is equivalent to 28.413 milliliters or 0.96076 US fluid ounces in the metric system.
  • A US fluid ounce is equal to one sixteenth of a US liquid pint in the US customary system of measurement. It is equivalent to 29.573 milliliters or 1.0408 UK fluid ounces in the metric system.
  • A US food labeling fluid ounce is exactly 30 milliliters.

History of Fluid Ounces

The origin of the term fluid ounce as a unit of measure is uncertain, but it may have derived from the Latin phrase fluida uncia, which means fluid ounce. Fluid ounces have been used since ancient times to store and transport various liquids and dry goods. The size and shape of fluid ounces 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 fluid ounces as a unit of measure dates back to the medieval times, when the European system of measurement was established. The standard size of these fluid ounces was based on the wine gallon, which was originally defined as the volume of eight pounds of wine at 62 °F. The fluid ounce was convenient for measuring and dividing smaller amounts of liquids and dry goods.

The use of fluid ounces as a unit of measure continued until the 20th century, when the metric system of measurement was adopted in most countries. The fluid ounce was gradually replaced by units such as liters, grams, etc. However, some countries and regions still use fluid ounces for certain types of liquids and dry goods, especially in the United States and the United Kingdom and Ireland and some Commonwealth nations.

How to Convert Fluid Ounces

To convert fluid ounces to other units of volume, one can use the following formulas:

  • To convert UK fluid ounces to liters: multiply by 0.028413

  • To convert UK fluid ounces to cubic inches: multiply by 1.7339

  • To convert UK fluid ounces to US fluid ounces: multiply by 0.96076

  • To convert UK fluid ounces to BOE: divide by 700

  • To convert US fluid ounces to liters: multiply by 0.029573

  • To convert US fluid ounces to cubic inches: multiply by 1.8047

  • To convert US fluid ounces to UK fluid ounces: multiply by 1.0408

  • To convert US fluid ounces to BOE: divide by 600

  • To convert US food labeling fluid ounces to liters: multiply by 0.03

  • To convert US food labeling fluid ounces to cubic inches: multiply by 1.831

  • To convert US food labeling fluid ounces to UK fluid ounces: multiply by 1.0559

  • To convert US food labeling fluid ounces to BOE: divide by 583

Where Fluid Ounces are Used

Fluid ounces are mainly used in some countries and regions that use the imperial system or the US customary system or the US food labeling 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, fluid ounces are not commonly used or recognized. Instead, they use units such as liters, grams, etc.

Example Conversions of Fluid Ounces to Other Units

Here are some examples of converting fluid ounces to other units of volume:

  • 1 UK fl oz = 0.028413 liters

  • 2 UK fl oz = 3.4678 cubic inches

  • 3 UK fl oz = 2.8823 US fl oz

  • 4 UK fl oz = 0.0057 BOE

  • 1 US fl oz = 0.029573 liters

  • 2 US fl oz = 3.6094 cubic inches

  • 3 US fl oz = 3.1224 UK fl oz

  • 4 US fl oz = 0.0067 BOE

  • 1 US food labeling fl oz = 0.03 liters

  • 2 US food labeling fl oz = 3.662 cubic inches

  • 3 US food labeling fl oz = 3.1677 UK fl oz

  • 4 US food labeling fl oz = 0.0069 BOE.

The US fluid ounce, defined as 1/128 US gallon, equals to 29.5735295625 milliliters.

Kilograms: A Unit of Weight

Definition of the Kilogram

A kilogram is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to the mass of the International Prototype of the Kilogram (IPK), a cylinder of platinum-iridium alloy stored at the International Bureau of Weights and Measures in France. One kilogram can also be written as kg or 1000 g.

History of the Kilogram

The kilogram was originally defined in 1795 during the French Revolution as the mass of one litre of water at 4 °C, which was determined to be 18841 grains. In 1799, the Kilogramme des Archives, a platinum artifact, replaced it as the standard of weight. In 1889, the IPK became the new standard of the unit of weight for the metric system and remained so for 130 years, until the current definition was adopted in 2019.

The kilogram, as well as other metric units of weight, such as the gram and the tonne, 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 kilogram was officially adopted by the International System of Units (SI) in 1960 as one of the seven base units.

How to Convert Kilograms

To convert kilograms to other units of weight, we need to use conversion factors that relate the kilogram to the desired unit. For example, to convert kilograms to pounds, we need to know that one pound is equal to 0.45359237 kg. Therefore, one kilogram is equal to 2.2046226218 pounds.

Here are some common conversion factors for kilograms:

  • 1 kg = 1000 g
  • 1 kg = 2.2046226218 lb
  • 1 kg = 35.27396195 oz
  • 1 kg = 0.001 t
  • 1 kg = 0.1574730444 st

To convert from other units of weight to kilograms, we need to use the inverse of these conversion factors. For example, to convert pounds to kilograms, we need to divide by 2.2046226218.

Where Kilograms are Used

The kilogram is a unit of weight that is widely used to measure the weight of objects and substances such as food, clothes, animals, metals and chemicals. For example, an adult human body has an average weight of about 62 kg.

The kilogram is also used to measure the weight of some physical quantities such as force, pressure and torque. For example, one newton (N) is equal to one kilogram times one meter per second squared (kg x m/s2).

Example Conversions of Kilograms to Other Units

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

  • 2 kg = 2 x 1000 g = 2000 g
  • 3 kg = 3 x 2.2046226218 lb = 6.6138678654 lb
  • 4 kg = 4 x 35.27396195 oz = 141.0958478 oz
  • 5 kg = 5 x 0.001 t = 0.005 t
  • 6 kg = 6 x 0.1574730444 st = 0.9448382664 st

Conclusion

The kilogram is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to the mass of the IPK, a cylinder of platinum-iridium alloy stored in France. The kilogram is widely used to measure the weight of objects and substances such as food, clothes, animals, metals and chemicals, as well as some physical quantities such as force, pressure and torque. To convert kilograms to other units of weight, we need to use conversion factors that relate the kilogram to the desired unit.

Kilograms also can be marked as kilogrammes in UK.
