The name of a number 10 3n+3, where n is greater than or equal to 1000, is formed by concatenating the names of the numbers of the form 10 3m+3, where m represents each group of comma-separated digits of n, with each but the last "-illion" trimmed to "-illi-", or, in the case of m = 0, either "-nilli-" or "-nillion".

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.
The ronnametre (SI symbol: Rm) is a unit of length in the metric system equal to 10 27 meters. [55] To help compare different orders of magnitude, this section lists distances starting at 1 Rm (10 27 m or 105.7 billion light-years). At this scale, expansion of the universe becomes significant.
Any real number can be written in the form m × 10 ^ n in many ways: for example, 350 can be written as 3.5 × 10 2 or 35 × 10 1 or 350 × 10 0. In normalized scientific notation (called "standard form" in the United Kingdom), the exponent n is chosen so that the absolute value of m remains at least one but less than ten ( 1 ≤ | m | < 10 ).

Sextillion may mean either of the two numbers (see long and short scales for more detail): . 1,000,000,000,000,000,000,000 (one thousand million million million; 10 21; SI prefix zetta-) for all short scale countries
The definition of units of weight above a pound differed between the customary and the imperial system - the imperial system employed the stone of 14 pounds, the hundredweight of 8 stone [Note 6] and the ton of 2240 pounds (20 hundredweight), while the customary system of units did not employ the stone but has a hundredweight of 100 pounds and ...
4×10 12 (4 trillion) The estimated time until the red dwarf star Proxima Centauri, the closest star to the Sun today, at a distance of 4.25 light-years, leaves the main sequence and becomes a white dwarf. [136] 10 13 (10 trillion) The estimated time of peak habitability in the universe, unless habitability around low-mass stars is suppressed ...
