Unit Explanations
Kilogramkg
Source UnitThe kilogram, abbreviated as kg, is the SI unit of mass and is defined as being equal to the mass of the International Prototype of the Kilogram, which is a platinum-iridium cylinder kept at the International Bureau of Weights and Measures (BIPM) in Sèvres, France. This definition was established in 1889 and was the only base unit defined by a physical object. However, in 2019, the definition of the kilogram was redefined in terms of fundamental constants, specifically the Planck constant (h), which is set at exactly 6.62607015 × 10^-34 joule seconds. This redefinition allows for more precise measurements and ensures that the kilogram remains consistent and reproducible over time.
Current Use
Today, the kilogram is widely used across the globe as the standard unit of mass in scientific, commercial, and everyday contexts. It is employed in various industries including manufacturing, agriculture, and healthcare. For instance, in the food industry, products are often sold by mass, measured in kilograms. In healthcare, medication dosages may also be prescribed based on the patient’s weight in kilograms. While most countries use the kilogram as part of the metric system, some countries, such as the United States, still use imperial units for certain applications, though the metric system is increasingly adopted in scientific and technical fields. The versatility of the kilogram makes it a vital unit in international trade and commerce.
Fun Fact
The kilogram was the first unit of measurement to be defined by a physical artifact.
Quarter (UK)qr
Target UnitThe quarter (UK) is a traditional unit of weight that is defined as one-fourth of a hundredweight. In the UK, a hundredweight is equivalent to 112 pounds, making a quarter equal to 28 pounds or approximately 12.7 kilograms. The quarter is mainly used in agriculture and trade, particularly for measuring grain and livestock. This unit's historical roots can be traced back to the medieval British system of weights and measures, which utilized various units for practical purposes in commerce and agriculture. Its use is primarily confined to the UK and some Commonwealth countries.
Current Use
Today, the quarter is predominantly used in the agricultural sector of the UK for weighing grains and livestock. It serves as a practical unit for farmers and traders who require an efficient means of measuring bulk goods. Additionally, it has relevance in historical contexts and traditional recipes, especially those involving large quantities of ingredients.
Fun Fact
The quarter was commonly used in the UK prior to the widespread adoption of the metric system in the 20th century.

Definition
The kilogram, abbreviated as kg, is the SI unit of mass and is defined as being equal to the mass of the International Prototype of the Kilogram, which is a platinum-iridium cylinder kept at the International Bureau of Weights and Measures (BIPM) in Sèvres, France. This definition was established in 1889 and was the only base unit defined by a physical object.

This redefinition allows for more precise measurements and ensures that the kilogram remains consistent and reproducible over time.
History & Origin
The kilogram originated in the late 18th century during the period of the French Revolution, as part of the efforts to standardize measurements across France and eventually the world. The need for a uniform measurement system became apparent in the wake of the Revolution, as varying local measures were causing confusion and inefficiency in trade and governance. Thus, the metric system was born, with the kilogram being one of its foundational units. The first kilogram was defined as the mass of one liter of water at its maximum density, which is approximately equal to 1,000 cubic centimeters. This practical approach to defining mass allowed for easier adoption across various sectors.
Etymology: The term 'kilogram' is derived from the Greek word 'kilo', meaning 'a thousand', and the French word 'gramme', which itself comes from the Late Latin 'gramma', meaning 'small weight'.

Its use is primarily confined to the UK and some Commonwealth countries.
History & Origin
The quarter (UK) originated from the medieval English system of weights and measures, where it was used to facilitate trade, especially in agriculture. This system was developed to standardize the measurement of goods such as grains and livestock, which were critical to the economy. The quarter was commonly used in markets and trade agreements, ensuring fair transactions.
Etymology: The term 'quarter' is derived from the Latin 'quartus,' meaning 'fourth.' This reflects its value as one-fourth of a hundredweight in the British system.
Current Use
Today, the quarter is predominantly used in the agricultural sector of the UK for weighing grains and livestock. It serves as a practical unit for farmers and traders who require an efficient means of measuring bulk goods. Additionally, it has relevance in historical contexts and traditional recipes, especially those involving large quantities of ingredients.
💡 Fun Facts
- •The quarter was commonly used in the UK prior to the widespread adoption of the metric system in the 20th century.
- •In Scotland, the quarter is sometimes referred to as a 'stane' in certain agricultural contexts.
- •The weight of a quarter (UK) can vary slightly based on the specific agricultural product being measured, such as different grains.
