Elementary charge, Electric charge
Elementary charge, symbol e, is the electric charge carried by a single proton, or equivalently, the negation (opposite) of the electric charge carried by a single electron and is a fundamental physical constant. To avoid confusion over its sign, e is sometimes called the elementary positive charge. This charge has a measured value of approximately 1.602176565(35)×10−19 coulombs. In the cgs system, e is 4.80320425(10)×10−10 statcoulombs.Read moreList of all Elementary charge to other electric charge units individual converters.
