CONT

Historically, nicotine yield has served as the metric for characterising the amount of nicotine emitted by different combustible cigarette products. Yield is defined as the mass of nicotine emitted through the mouth end of a tobacco product per unit of consumption(e. g., milligrams of nicotine per cigarette; mg/cig).

CONT

Le fumeur est capable d'obtenir la quantité de nicotine dont il a besoin, quel que soit le type de cigarettes fumées, même avec les cigarettes dites «légères». Ces cigarettes ne sont dénommées ainsi que parce que le rendement en nicotine mesuré par une machine à fumer est diminué.

Record 9 2011-07-11

English

Subject field(s)
  • Atmospheric Physics
  • Metrology and Units of Measure
DEF

The ratio of the mass of water vapor actually in the air to a unit mass of air... usually expressed in the metric system.

OBS

A kilogram (1000 grams) of air of which 12 grams are water vapor has a specific humidity of 12 grams per kilogram.

OBS

A closely related term is mixing ratio, which is the mass of water vapor per unit mass of dry air. The mixing ratio is, in a sense, a recipe for an admixture of water vapor and dry air. A value of 12 grams per kilogram would entail a total of 1012 grams for the mixture. For most conditions, the specific humidity and the mixing ratio differ insignificantly.

OBS

specific humidity: term standardized by ISO.

French

Domaine(s)
  • Physique de l'atmosphère
  • Unités de mesure et métrologie
DEF

Masse de vapeur d'eau contenue dans l'unité de masse d'air humide généralement exprimée en grammes de vapeur par kilogramme d'air humide.

OBS

Ne pas confondre avec le rapport de mélange (grammes de vapeur par kilogramme d'air sec) qui est une approximation de l'humidité spécifique; ces deux notions sont néanmoins souvent confondues dans la pratique parce que la différence entre ces deux mesures est souvent inférieure aux simples erreurs dues à la manipulation des instruments qui servent à les mesurer.

Record 10 2007-10-25

English

Subject field(s)
  • Electromagnetic Radiation
DEF

The speed at which light and other magnetic waves travel through empty space.

CONT

The velocity of light is 2.9979 x 108 m/s.

CONT

The speed of light in a vacuum is an important physical constant denoted by the letter c for "constant" or the Latin word "celeritas" meaning "swiftness". It is the speed of all electromagnetic radiations, including visible light, in a vacuum. More generally, it is the speed of anything having zero rest mass.... In metric units, the speed of light is exactly 299, 792, 458 metres per second(1, 079, 252, 848. 8 km/h). The fundamental SI unit of length, the metre, has been defined since October 21, 1983, as the distance light travels in a vacuum in 1/299, 792, 458 of a second; any increase in the precision of the measurement of the speed of light would refine the definition of the metre, but not alter the numerical value of c. The approximate value of 3x108 m/s is commonly used in rough estimates. In imperial units, the speed of light is about 670, 616, 629. 2 miles per hour or 983, 571, 056 feet per second, which is about 186, 282, 397 miles per second, or roughly one foot per nanosecond. The speed of light when it passes through a transparent or translucent material medium, like glass or air, is slower than its speed in a vacuum. The ratio of c to the observed phase velocity is called the refractive index of the medium.

Record 11 2007-01-19

English

Subject field(s)
  • Metrology and Units of Measure
  • Gemmology
  • Diamond Industry
CONT

Describre carat : a) metric unit of mass of gem stones; b) 1 carat(ct)=200 mg=100 points=4 grainer : 0. 25 ct=1 grainer; c) mass of smaller diamonds is typically expressed in points, e. g., 5-pointer(0. 05 ct).

OBS

In 1913, carat weight was standardized internationally and adapted to the metric system.

OBS

Sometimes in the jewelry trade, the term size is used as a synonym for carat weight. This is because small round diamonds having the same weight also look the same size and have similar diameters.

French

Domaine(s)
  • Unités de mesure et métrologie
  • Gemmologie
  • Industrie diamantaire
DEF

Unité de poids pour les diamants, les pierres précieuses et les perles. Originalement basé sur la graine du caroubier il a varié de pays en pays jusqu'en 1907 alors qu'il a été standardisé à 1/5 de gramme, 0,200 gramme ou 200 milligrammes le carat métrique.

CONT

Le poids d'un diamant s'exprime en carats métriques; il en est de même pour les plupart des pierres précieuses. Un carat métrique est égal a 0,200 gramme (200 milligrammes ou 1/5 de gramme). Un carat se divise en 100 unités égales appelées «points».

OBS

En 1913, le poids du carat a été normalisé dans le monde entier et relié au système métrique.

OBS

Dans le domaine de la bijouterie, on parle souvent indistinctement de la grosseur d'un diamant et de son poids en carats. Cela s'explique par le fait que les petits diamants ronds dont les poids sont semblables paraissent tous de mêmes grosseur et diamètre.
