  2. Alcohol measurements - Wikipedia

    en.wikipedia.org/wiki/Alcohol_measurements

    Alcohol measurements are units of measurement for determining amounts of beverage alcohol.Alcohol concentration in beverages is commonly expressed as alcohol by volume (ABV), ranging from less than 0.1% in fruit juices to up to 98% in rare cases of spirits.

  3. Food energy - Wikipedia

    en.wikipedia.org/wiki/Food_energy

    For example, the values for glucose, sucrose, and starch are 15.57, 16.48 and 17.48 kilojoules per gram (3.72, 3.94 and 4.18 kcal/g) respectively. The differing energy density of foods (fat, alcohols, carbohydrates and proteins) lies mainly in their varying proportions of carbon, hydrogen, and oxygen atoms.

  4. Density - Wikipedia

    en.wikipedia.org/wiki/Density

    The bulk volume of a material —inclusive of the void space fraction— is often obtained by a simple measurement (e.g. with a calibrated measuring cup) or geometrically from known dimensions. Mass divided by bulk volume determines bulk density. This is not the same thing as the material volumetric mass density.

  5. Sugar - Wikipedia

    en.wikipedia.org/wiki/Sugar

    For added sugars, the guidance is that 100% DV should not be exceeded. 100% DV is defined as 50 grams. For a person consuming 2000 calories a day, 50 grams is equal to 200 calories and thus 10% of total calories—the same guidance as the WHO. [152] To put this in context, most 12-US-fluid-ounce (355 ml) cans of soda contain 39 grams of sugar.

    Paris (French pronunciation: ⓘ) is the capital and largest city of France.With an estimated population of 2,048,472 residents in January 2025 [3] in an area of more than 105 km 2 (41 sq mi), [4] Paris is the fourth-most populous city in the European Union, the ninth-most populous city in Europe and the 30th most densely populated city in the world in 2022.

  7. Orders of magnitude (mass) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(mass)

    An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.

  8. Half-life - Wikipedia

    en.wikipedia.org/wiki/Half-life

    N 0 is the initial quantity of the substance that will decay (this quantity may be measured in grams, moles, number of atoms, etc.), N(t) is the quantity that still remains and has not yet decayed after a time t, t ½ is the half-life of the decaying quantity, τ is a positive number called the mean lifetime of the decaying quantity,

  9. Russian ruble - Wikipedia

    en.wikipedia.org/wiki/Russian_ruble

    By the end of the 18th century, the ruble was set to 4 zolotnik 21 dolya (or 4 21 ⁄ 96 zolotnik, almost exactly equal to 18 grams) of pure silver or 27 dolya (almost exactly equal to 1.2 g (0.039 ozt)) of pure gold, with a ratio of 15:1 for the values of the two metals.
