  2. Scientific notation - Wikipedia

    en.wikipedia.org/wiki/Scientific_notation

    Converting a number from scientific notation to decimal notation, first remove the × 10 n on the end, then shift the decimal separator n digits to the right (positive n) or left (negative n). The number 1.2304 × 10 6 would have its decimal separator shifted 6 digits to the right and become 1,230,400 , while −4.0321 × 10 −3 would have its ...

  3. Alcohol by volume - Wikipedia

    en.wikipedia.org/wiki/Alcohol_by_volume

    Alcohol by volume (abbreviated as alc/vol or ABV) is a standard measure of the volume of alcohol contained in a given volume of an alcoholic beverage, expressed as a volume percent. [1] [2] [3] It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.5 imp fl oz; 3.4 US fl oz) of solution at 20 °C (68 °F).

  4. Repeating decimal - Wikipedia

    en.wikipedia.org/wiki/Repeating_decimal

    A repeating decimal or recurring decimal is a decimal representation of a number whose digits are eventually periodic (that is, after some place, the same sequence of digits is repeated forever); if this sequence consists only of zeros (that is if there is only a finite number of nonzero digits), the decimal is said to be terminating, and is not considered as repeating.

  5. Grade (slope) - Wikipedia

    en.wikipedia.org/wiki/Grade_(slope)

    Grade is usually expressed as a percentage, but this is easily converted to the angle α by taking the inverse tangent of the standard mathematical slope, which is rise / run or the grade / 100. If one looks at red numbers on the chart specifying grade, one can see the quirkiness of using the grade to specify slope; the numbers go from 0 for ...

  6. Percentage in point - Wikipedia

    en.wikipedia.org/wiki/Percentage_in_point

    The major currencies (except the Japanese yen) are traditionally priced to four decimal places, and a pip is one unit of the fourth decimal place: for dollar currencies this is to 1/100 of a cent. For the yen, a pip is one unit of the second decimal place, because the yen is much closer in value to one hundredth of other major currencies. [3]

  7. Decimalisation - Wikipedia

    en.wikipedia.org/wiki/Decimalisation

    Decimalisation or decimalization (see spelling differences) is the conversion of a system of currency or of weights and measures to units related by powers of 10.. Most countries have decimalised their currencies, converting them from non-decimal sub-units to a decimal system, with one basic currency unit and sub-units that are to a power of 10, most commonly 100, and exceptionally 1000; and ...

  8. Visual acuity - Wikipedia

    en.wikipedia.org/wiki/Visual_acuity

    Otherwise, using the foot, visual acuity is expressed relative to 20/20. For all practical purposes, 20/20 vision is equivalent to 6/6. In the decimal system, acuity is defined as the reciprocal value of the size of the gap (measured in arc minutes) of the smallest Landolt C, the orientation of which can be reliably identified. A value of 1.0 ...

  9. Sustainable Development Goal 12 - Wikipedia

    It has one indicator: Indicator 12.c.1 is the: "(a) Amount of fossil-fuel subsidies as a percentage of GDP; and (b) amount of fossil fuel subsidies as a proportion of the total national expenditure on fossil fuels". [1] Global fossil fuel subsidies in 2018 were $400 billion. [5]: 14 This was double the subsidies for renewable energy. [5]: 14
