By using the value of c, as well as an accurate measurement of the second, one can establish a standard for the metre. [ 13 ] The particular value chosen for the speed of light provided a more accurate definition of the metre that still agreed as much as possible with the definition used before 1983.
The SI defines the coulomb as "the quantity of electricity carried in 1 second by a current of 1 ampere". Then the value of the elementary charge e is defined to be 1.602 176 634 × 10 −19 C. [3]
C-value is the amount, in picograms, of DNA contained within a haploid nucleus (e.g. a gamete) or one half the amount in a diploid somatic cell of a eukaryotic organism. In some cases (notably among diploid organisms), the terms C-value and genome size are used interchangeably; however, in polyploids the C-value may represent two or more genomes contained within the same nucleus.
In unit systems where force is a derived unit, like in SI units, g c is equal to 1. In unit systems where force is a primary unit, like in imperial and US customary measurement systems, g c may or may not equal 1 depending on the units used, and value other than 1 may be required to obtain correct results.

Value 9.648 533 212 331 001 84 × 10 4 C⋅mol −1 In physical chemistry , the Faraday constant (symbol F , sometimes stylized as ℱ) is a physical constant defined as the quotient of the total electric charge ( q ) by the amount ( n ) of elementary charge carriers in any given sample of matter: F = q / n ; it is expressed in units of ...
In English orthography, c generally represents the "soft" value of / s / before the letters e (including the Latin-derived digraphs ae and oe , or the corresponding ligatures æ and œ ), i , and y , and a "hard" value of / k / before any other letters or at the end of a word.
