A Gregorian year, which takes into account the 100 vs. 400 leap year exception rule of the Gregorian calendar, is 365.2425 days (the average length of a year over a 400–year cycle), resulting in 0.1 years being a period of 36.52425 days (3 155 695.2 seconds; 36 days, 12 hours, 34 minutes, 55.2 seconds).
These include the equivalence of mass and energy (E = mc 2), length contraction (moving objects shorten), [Note 9] and time dilation (moving clocks run more slowly). The factor γ by which lengths contract and times dilate is known as the Lorentz factor and is given by γ = (1 − v 2 /c 2) −1/2, where v is the speed of the object.
The repeating decimal commonly written as 0.999... represents exactly the same quantity as the number one. Despite having the appearance of representing a smaller number, 0.999... is a symbol for the number 1 in exactly the same way that 0.333... is an equivalent notation for the number represented by the fraction 1 ⁄ 3.

The minute of arc (or MOA, arcminute, or just minute) is 1 / 60 of a degree = 1 / 21,600 turn. It is denoted by a single prime ( ′ ). For example, 3° 30′ is equal to 3 × 60 + 30 = 210 minutes or 3 + 30 / 60 = 3.5 degrees. A mixed format with decimal fractions is sometimes used, e.g., 3° 5.72′ = 3 + 5.72 / 60 ...
Volume was measured in ngogn (equal to 1000 cubic potrzebies), mass in blintz (equal to the mass of 1 ngogn of halva, which is "a form of pie [with] a specific gravity of 3.1416 and a specific heat of .31416"), and time in seven named units (decimal powers of the average earth rotation, equal to 1 "clarke").
The most commonly reported ancestries of White Americans include English (12.5%), German (7.6%), Irish (5.3%), Italian (3.2%), and Polish (1.3%). [20] It is difficult to track full or partial ancestry from Spain in White Hispanics , Mestizos , or Mulattoes since people of direct Spanish descent are also classified as Hispanic, and though the ...
According to a report published by the Water Footprint organization in 2010, a single kilogram of beef requires 15 thousand litres (3.3 × 10 ^ 3 imp gal; 4.0 × 10 ^ 3 US gal) of water; however, the authors also make clear that this is a global average and circumstantial factors determine the amount of water used in beef production.
