I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.
What we do. Every page goes through several hundred of perfecting techniques; in live mode. Quite the same Wikipedia. Just better.

The statcoulomb (statC) or franklin (Fr) or electrostatic unit of charge (esu) is the physical unit for electrical charge used in the esu-cgs (centimetre–gram–second system of units) and Gaussian units. It is a derived unit given by

1 statC = dyn1/2 cm = cm3/2 g1/2 s−1.

It can be converted using

1 newton = 105 dyne
1 cm = 10−2 m

The SI unit of charge is the coulomb (C). The conversion between C and statC is:

  • 1 C = 2997924580 statC3.00×109 statC
  • 1 statC ≈ 3.33564×10−10 C.

The number 2997924580 is 10 times the value of the speed of light expressed in meters/second or, in other words, the speed of light in decimeters per second.

Definition and relation to cgs base units

The statcoulomb is defined as follows: if two stationary objects each carry a charge of 1 statC and are 1 cm apart, they will electrically repel each other with a force of 1 dyne. This repulsion is governed by Coulomb's law, which in the Gaussian-cgs system states:

where F is the force, q1 and q2 are the two charges, and r is the distance between the charges.

In SI units, the parallel statement for the force between two charges is:

where ε0 is the electric constant. The effect of the Gaussian-cgs definition is to fold the "1/4πε0" factor into the definition of the statcoulomb by setting it equal to unity in terms of length, mass, and time; which results in the Gaussian unit of electric charge possessing the cgs dimensions of L3/2 M1/2 T−1.
