To help compare different orders of magnitude, this section lists distances starting at 1 Ym (10 24 m or 105.702 million light-years). 1.2 Ym – 127 million light-years – distance to the closest observed gamma ray burst GRB 980425; 1.3 Ym – 137 million light-years – distance to the Centaurus Cluster of galaxies, the nearest large ...
Visualization of 1 trillion (short scale) A Rubik's cube, which has about 43 trillion (long scale) possible positions. Trillion is a number with two distinct definitions: 1,000,000,000,000, i.e. one million million, or 10 12 (ten to the twelfth power), as defined on the short scale. This is now the meaning in both American and British English.
1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.

[3] [4] In standard form, it is written as 1 × 10 9. The metric prefix giga indicates 1,000,000,000 times the base unit. Its symbol is G. One billion years may be called an eon in astronomy or geology. Previously in British English (but not in American English), the word "billion" referred exclusively to a million millions (1,000,000,000,000 ...
For example, 1 and 1.02 are within an order of magnitude. So are 1 and 2, 1 and 9, or 1 and 0.2. However, 1 and 15 are not within an order of magnitude, since their ratio is 15/1 = 15 > 10. The reciprocal ratio, 1/15, is less than 0.1, so the same result is obtained.
Area: A square a thousand objects or units on a side contains a million such objects or square units, so a million holes might be found in less than three square yards of window screen, or similarly, in about one half square foot (400–500 cm 2) of bed sheet cloth. A city lot 70 by 100 feet is about a million square inches.
100 d (1 hd) 100 days, roughly equivalent to 1/4 of a year (91.25 days). In Chinese tradition "bǎi rì" is the hundredth day after one's birth, also called Baby's 100 Days Celebration. semester: 18 weeks: A division of the academic year. [6] Literally "six months", also used in this sense. lunar year: 354.37 d: year: 12 mo: 365 or 366 d ...
