If each book had a mass of 100 grams, all of them would have a total mass of 10 93 kilograms. In comparison, Earth 's mass is 5.97 × 10 24 kilograms, [ 5 ] the mass of the Milky Way galaxy is estimated at 1.8 × 10 42 kilograms, [ 6 ] and the total mass of all the stars in the observable universe is estimated at 2 × 10 52 kg.
Mathematics – Bases: 9,439,829,801,208,141,318 (≈9.44 × 10 18) is the 10th and (by conjecture) largest number with more than one digit that can be written from base 2 to base 18 using only the digits 0 to 9, meaning the digits for 10 to 17 are not needed in bases greater than 10. [51]
That means 95,676,260,903,887,607 primes [3] (nearly 10 17), but they were not stored. There are known formulae to evaluate the prime-counting function (the number of primes smaller than a given value) faster than computing the primes. This has been used to compute that there are 1,925,320,391,606,803,968,923 primes (roughly 2 × 10 21) smaller ...
[7] [8] [9] It is widely believed, [10] but not proven, that no odd perfect numbers exist; numerous restrictive conditions have been proven, [10] including a lower bound of 10 1500. [11] The following is a list of all 52 currently known (as of January 2025) Mersenne primes and corresponding perfect numbers, along with their exponents p.
To put in perspective the size of a googol, the mass of an electron, just under 10 −30 kg, can be compared to the mass of the visible universe, estimated at between 10 50 and 10 60 kg. [5] It is a ratio in the order of about 10 80 to 10 90 , or at most one ten-billionth of a googol (0.00000001% of a googol).
For a number written in scientific notation, this logarithmic rounding scale requires rounding up to the next power of ten when the multiplier is greater than the square root of ten (about 3.162). For example, the nearest order of magnitude for 1.7 × 10 8 is 8, whereas the nearest order of magnitude for 3.7 × 10 8 is 9.
Global net primary production – the total mass of carbon fixed in organic compounds by photosynthesis each year on Earth [121] 7.2 × 10 14 kg Total carbon stored in Earth's atmosphere [122] 10 15 exagram (Eg) 2.0 × 10 15 kg Total carbon stored in the terrestrial biosphere [123] 3.5 × 10 15 kg Total carbon stored in coal deposits worldwide ...
