The Coulomb:

The standard unit of electric charge amount is the coulomb, represented by C. This is the electric charge which exists in a congregation of around 6.241506 x 10¹⁸ electrons. It also occurs to be the electric charge contained in that number of antiprotons, protons, or positrons (i.e., antielectrons).

Whenever you walk along a carpet with hard-soled shoes in the winter or anywhere the humidity is extremely low, your body makes up a static electric charge which can be expressed in coulombs (or more probable a fraction of one coulomb). Decreased to base units in SI, one coulomb is come to one ampere-second (1 A . s).
