THE COULOMB
The standard unit of electric charge quantity is the coulomb, symbolized C. This is the electric charge that exists in a congregation of approximately 6.241506 × 1018 electrons. It also happens to be the electric charge contained in that number of protons, antiprotons, or positrons (antielectrons). When you walk along a carpet with hard-soled shoes in the winter or anywhere the humidity is very low, your body builds up a static electric charge that can be expressed in coulombs (or more likely a fraction of one coulomb). Reduced to base units in SI, one coulomb is equal to one ampere-second (1 A . s).
