スタットクーロン（statcoulomb, 記号 statC）は、CGS 静電単位系 (esu)・ガウス単位系における電荷（電気量）の単位である。静電単位（せいでんたんい、esu、electrostatic unit）ともいう。
Hukum Coulomb adalah hukum yang menjelaskan hubungan di antara dua muatan listrik. Hubungan yang dibahas oleh hukum Coulomb berkaitan dengan pengaruh ukuran muatan listrik terhadap gaya yang timbul pada jarak tertentu.
采用厘米-克-秒制，单位电荷（ esu ），又称为静库仑（ statcoulomb ），定义为使库仑常数 为1的数值。 库仑定律的纯量公式表明，力量的大小直接地与两个点电荷的电量成正比，又与两个点电荷之间距离的平方成反比。
The elementary charge, usually denoted by e, is a fundamental physical constant, defined as the electric charge carried by a single proton or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e.
The statcoulomb is defined as follows: if two objects each carry a charge of 1 statC and are 1 cm apart, they will repel each other with a force of 1 dyne. As a result, in the electrostatic cgs system, Coulomb's law describing the force F between two charges q 1 and q 2 a distance r apart takes the simple form:
In the CGS system, the unit of the H-field is the oersted and the unit of the B-field is the gauss.In the SI system, the unit ampere per meter (A/m), which is equivalent to newton per weber, is used for the H-field and the unit of tesla is used for the B-field.
The ESU unit of charge, franklin (Fr), also known as statcoulomb or esu charge, is therefore defined as follows: [14] two equal point charges spaced 1 centimetre apart are said to be of 1 franklin each if the electrostatic force between them is 1 dyne .
