The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
The number of neuronal connections in the human brain (estimated at 10 14), or 100 trillion/100 T; The Avogadro constant is the number of "elementary entities" (usually atoms or molecules) in one mole; the number of atoms in 12 grams of carbon-12 – approximately 6.022 × 10 23, or 602.2 sextillion/60.2Sx.
There are one billion cubic millimetres in a cubic metre, and a billion cubic metres in a cubic kilometre. A billion grains of table salt or granulated sugar would occupy a volume of about 2.5 cubic feet (0.071 m 3). A billion cubic inches would be a volume comparable to a large commercial building slightly larger than a typical supermarket.
See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
Billion is a word for a large number, and it has two distinct definitions: 1,000,000,000 , i.e. one thousand million , or 10 9 (ten to the ninth power ), as defined on the short scale . This is now the most common sense of the word in all varieties of English; it has long been established in American English and has since become common in ...
The naming procedure for large numbers is based on taking the number n occurring in 10 3n+3 (short scale) or 10 6n (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix -illion. In this way, numbers up to 10 3·999+3 = 10 3000 (short scale) or 10 6·999 = 10 5994 (long scale
The Chudnovsky algorithm is a fast method for calculating the digits of π, based on Ramanujan's π formulae.Published by the Chudnovsky brothers in 1988, [1] it was used to calculate π to a billion decimal places.
The same number, however, would be used if the last two digits were also measured precisely and found to equal 0 – seven significant figures. When a number is converted into normalized scientific notation, it is scaled down to a number between 1 and 10. All of the significant digits remain, but the placeholding zeroes are no longer required.
