Unit Explanations
Stonest
Source UnitThe stone is a unit of weight that is traditionally used in the British Isles. It is equivalent to 14 pounds avoirdupois, or approximately 6.35029 kilograms. The unit was historically used for weighing agricultural commodities, animals, and people. While it is not commonly used in many countries today, it remains a popular measure in the UK and Ireland for personal body weight. The stone is part of the imperial system of measurements and is not recognized by the International System of Units (SI).
Current Use
Today, the stone is mainly used in the UK and Ireland for expressing personal body weight. Despite the global shift towards the metric system, many people in these regions prefer using stones and pounds rather than kilograms. In some sports like wrestling and boxing, body weights are still sometimes given in stones.
Fun Fact
The stone is still colloquially used in the UK despite metrication.
Kilogramkg
Target 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 à 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 patientâs 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.
Stone to Kilograms Converter
To convert stone to kilograms, multiply the stone value by 6.35029. Since 1 stone = 14 pounds, and 1 pound = 0.453592 kg, this gives: 14 Ă 0.453592 = 6.35029 kg. Example: 12 stone Ă 6.35029 = 76.2 kg.
Stone (st)
Definition
A stone is a British unit of mass equal to 14 avoirdupois pounds (6.35029 kg).
Origins & History
The stone originated in medieval England where it was used for trading wool. While once varying by commodity (ranging from 4 to 26 pounds), the stone was standardized at 14 pounds in 1824.
Kilogram (kg)
Definition
The kilogram is the fundamental unit of mass in the metric system, defined by the Planck constant.
Origins & History
Created during the French Revolution to replace inconsistent local units, the kilogram became the worldwide standard for mass in science and commerce.

Definition
The stone is a unit of weight that is traditionally used in the British Isles. It is equivalent to 14 pounds avoirdupois, or approximately 6.35029 kilograms. The unit was historically used for weighing agricultural commodities, animals, and people. While it is not commonly used in many countries today, it remains a popular measure in the UK and Ireland for personal body weight. The stone is part of the imperial system of measurements and is not recognized by the International System of Units (SI).
History & Origin
The stone has ancient origins, with its use dating back to Roman times when trade and commerce required a standardized unit for weight. The term 'stone' was derived from the use of actual stones as counterweights in balance scales. Over centuries, the weight of a stone varied regionally until it was standardized in England as 14 pounds by the mid-19th century.
Etymology: The word 'stone' comes from the Old English 'stÄn', which means a small rock or pebble.
Current Use
Today, the stone is mainly used in the UK and Ireland for expressing personal body weight. Despite the global shift towards the metric system, many people in these regions prefer using stones and pounds rather than kilograms. In some sports like wrestling and boxing, body weights are still sometimes given in stones.
đĄ Fun Facts
- â˘The stone is still colloquially used in the UK despite metrication.
- â˘In medieval times, different regions used stones of different weights, ranging from 5 to 40 pounds.
- â˘The term 'stone's throw' originates from the use of stones as a measure of distance.

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. 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 à 10^-34 joule seconds. 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'.
Current Use

- â˘The kilogram was the first unit of measurement to be defined by a physical artifact.
- â˘The International Prototype of the Kilogram lost mass over time, leading to the redefinition in 2019.
- â˘The kilogram is the only SI base unit with a prefix ('kilo') included in its name.
