Het SI-systeem definieerde de kilogram tot november 2018 als gelijk aan de massa van een internationaal prototype ("IPK", International Prototype of the Kilogram, of "le Grand K"), dat van een legering van platina en iridium is gemaakt en bewaard wordt op het Bureau international des poids et mesures (BIPM) (het internationale bureau van gewichten en maten) in het Franse …

The kilogram-force (kgf or kg F), or kilopond (kp, from Latin: pondus, lit. 'weight'), is a non-standard gravitational metric unit of force.It does not comply with the International System of Units (SI) and is deprecated for most uses. The kilogram-force is equal to the magnitude of the force exerted on one kilogram of mass in a 9.806 65 m/s 2 gravitational field (standard gravity, a ...

The International Prototype of the Kilogram (referred to by metrologists as the IPK or Le Grand K; sometimes called the ur-kilogram, or urkilogram, particularly by German-language authors writing in English:30: 64 ) is an object that was used to define the magnitude of the mass of the kilogram from 1889, when it replaced the Kilogramme des Archives, until 2019, when it was …

Kopi luwak is a coffee that consists of partially digested coffee cherries, which have been eaten and defecated by the Asian palm civet (Paradoxurus hermaphroditus).It is also called civet coffee.The cherries are fermented as they pass through a civet's intestines, and after being defecated with other fecal matter, they are collected. Asian palm civets are increasingly caught …

Definition. The specific heat capacity of a substance, usually denoted by or s, is the heat capacity of a sample of the substance, divided by the mass of the sample: = = where represents the amount of heat needed to uniformly raise the temperature of the sample by a small increment .. Like the heat capacity of an object, the specific heat capacity of a substance may vary, …

The calorie is a unit of energy. For historical reasons, two main definitions of "calorie" are in wide use. The large calorie, food calorie, or kilogram calorie was originally defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius (or one kelvin). The small calorie or gram calorie was defined as the amount of heat needed to cause …

The kilogram (also kilogramme) is the unit of mass in the International System of Units (SI), having the unit symbol kg.It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means 'one thousand grams'.. As of the 2019 redefinition of the SI base units, the kilogram is defined in terms of the second and the …

The coconut crab (Birgus latro) is a species of terrestrial hermit crab, also known as the robber crab or palm thief.It is the largest terrestrial arthropod in the world, with a weight of up to 4.1 kg (9 lb). It can grow to up to 1 m (3 ft 3 in) in width from the tip of one leg to the tip of another. It is found on islands across the Indian Ocean, and parts of the Pacific Ocean as far east as ...

Properties and grades. Kerosene is a low-viscosity, clear liquid formed from hydrocarbons obtained from the fractional distillation of petroleum between 150 and 275 °C (300 and 525 °F), resulting in a mixture with a density of 0.78–0.81 g/cm 3.It is miscible in petroleum solvents but immiscible in water. It is composed of hydrocarbon molecules that typically contain between 6 …
