You have likely experienced "static shock" recently.  The magnitude of charge transferred when you walk across a carpet, reach out and touch a doorknob, and unintentionally give yourself that static shock is around 1.88 nC (nC stands for nano-Coulomb).  In units of Giga-electrons, about how many electrons are transferred when you experience static shock?
