  2. Percentage - Wikipedia

    en.wikipedia.org/wiki/Percentage

    It is not correct to divide by 100 and use the percent sign at the same time; it would literally imply division by 10,000. For example, 25% = ⁠ 25 / 100 ⁠ = 0.25, not ⁠ 25% / 100 ⁠, which actually is ⁠ 25 ⁄ 100 / 100 ⁠ = 0.0025. A term such as ⁠ 100 / 100 ⁠ % would also be incorrect, since it would be read as 1 percent, even ...

    en.wikipedia.org/wiki/Milliradian

    A common adjustment value in firearm sights is 1 cm at 100 meters which equals ⁠ 10 mm / 100 m ⁠ = ⁠ 1 / 10 ⁠ mrad. The true definition of a milliradian is based on a unit circle with a radius of one and an arc divided into 1,000 mrad per radian, hence 2,000 π or approximately 6,283.185 milliradians in one turn , and rifle scope ...

    The number , whose typical value is close to but not greater than 1, is sometimes given in the form (or as a percentage % ()), where is a small positive number, often 0.05. In many applications, confidence intervals that have exactly the required confidence level are hard to construct, but approximate intervals can be computed.

    If the mass of an object is estimated as 3.78 ± 0.07 kg, so the actual mass is probably somewhere in the range 3.71 to 3.85 kg, and it is desired to report it with a single number, then 3.8 kg is the best number to report since its implied uncertainty ± 0.05 kg gives a mass range of 3.75 to 3.85 kg, which is close to the measurement range.

  7. Rate of return - Wikipedia

    To calculate the capital gain for US income tax purposes, include the reinvested dividends in the cost basis. The investor received a total of $4.06 in dividends over the year, all of which were reinvested, so the cost basis increased by $4.06. Cost Basis = $100 + $4.06 = $104.06; Capital gain/loss = $103.02 − $104.06 = -$1.04 (a capital loss)

  9. Brix - Wikipedia

    en.wikipedia.org/wiki/Brix

    Degrees Brix (symbol °Bx) is a measure of the dissolved solids in a liquid, based on its specific gravity, and is commonly used to measure dissolved sugar content of a solution. [1] One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. If the solution contains dissolved ...
