The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). It is equal to the electric charge delivered by a 1 ampere current in 1 second and is defined in terms of the elementary charge e, at about 6.241 509 × 10 18 e.
Coulomb, unit of electric charge in the metre-kilogram-second-ampere system, the basis of the SI system of physical units. It is abbreviated as C. The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere. Named for the 18th–19th-century French.

The coulomb (symbol: C) is the International System of Units (SI) unit of electric charge. The coulomb was defined as the quantity of electricity transported in one second by a current of one ampere: 1 C = 1 A × 1 s. How many elementary charges are in a coulomb? One coulomb is the charge of approximately 6241509074460762607.776 elementary charges.
The SI derived unit of electric charge is the coulomb (C) named after French physicist Charles-Augustin de Coulomb. In electrical engineering it is also common to use the ampere-hour (A⋅h). In physics and chemistry it is common to use the elementary charge ( e) as a unit.
Coulomb (C) is the SI unit of charge. Hence it can be used the express the charge possessed by any body, not necessarily a proton or electron. In this case, a proton possesses a charge of +1.602176634×10^−19 C and electron of -1.602176634×10^−19 C (positive and negative respectively) Hope that helped.

The SI unit for charge is the coulomb (C), with protons and electrons having charges of opposite sign but equal magnitude; the magnitude of this basic charge is \(\displaystyle e≡1.602×10^{−19}C\)
Apr 2, 2024 · One coulomb consists of 6.24 × 10 18 natural units of electric charge, such as individual electrons or protons. From the definition of the ampere, the electron itself has a negative charge of 1.602176634 × 10 −19 coulomb.
