Electric charge is a fundamental property of matter, representing the amount of electricity in an object. It can be positive or negative.

1 abcoulomb = 10 s*A; The abcoulomb is a unit of electric charge, equivalent to 10^6 coulombs. It is used to measure large amounts of charge in electrical systems.

1 Clm = 1.0 s*A; The "clm" is a unit of electric charge, also known as coulomb. It represents the amount of charge passing a point in one second.

1 coulomb = 1 s*A; The coulomb is the SI unit of electric charge, representing the amount of charge passing a point in a circuit per second when a current of one ampere is flowing.

1 ec = 1.602176634e-19 s*A (#4 of 7 SI Defining constants); The "ec" unit, known as electron charge, is a fundamental unit of electric charge in the SI system. It is the charge of a single electron and is the 4th of 7 defining constants in the SI system.

1 fdy = 96485.31 s*A; "fdy" is a unit of electric charge and represents a specific amount of charge.

1 fr = 3.335641e-10 s*A; The physical unit "fr" is a unit of electric charge. It is used to measure the amount of charge present in a system.
