Convert Statampere to CGS Electromagnetic Unit of Current (EMU) (stA to emu)

Statampere (stA) and CGS Electromagnetic Unit of Current (EMU) (emu) are both units of current. With the conversion form below, you can effortlessly and accurately convert statampere to cgs electromagnetic unit of current (emu). This free online calculator tool makes it simple and easy to perform the conversion from stA unit to the emu unit.

Electric current is the rate at which electric charge flows through a conductor. It is measured in amperes (A), the SI base unit named after French physicist André-Marie Ampère. One ampere equals one coulomb of charge passing a point per second (1 A = 1 C/s). Current can flow as direct current (DC)—in a single direction—or as alternating current (AC), which periodically reverses direction and powers most homes and businesses worldwide.

A statampere (statA) is a unit of electric current from the CGS electrostatic system. One statampere equals approximately 3.336 × 10^-10 amperes in SI units—significantly smaller than the SI ampere, reflecting the different electromagnetic conventions of the CGS system. The statampere developed as part of Gaussian CGS notation used in theoretical physics, particularly in older classical electromagnetism textbooks. The unit remains in some theoretical physics literature and historical scientific works, but SI units (amperes) are now universally standard in electrical engineering, instrumentation, and contemporary scientific practice. Modern researchers encounter statampere notation primarily when reviewing historical literature or studying classical field theory.

The CGS electromagnetic unit of current (EMU) is identical to the abampere, equal to 10 amperes in SI units. The term "EMU" refers to electromagnetic units within the CGS system, which defined electrical quantities based on the measurable effects of electromagnetic forces. The EMU system was used extensively in the 19th and early 20th centuries before the SI system became the international standard. The unit appears occasionally in historical scientific literature and specialized physics texts, but the specific EMU terminology is rarely used in modern applications. Contemporary science and engineering have adopted SI units exclusively, making EMU notation primarily a historical reference encountered when reviewing classical scientific texts.
