Statampere to Milliampere Converter

A statampere (statA) is a unit of electric current in the electrostatic CGS system, equal to approximately 3.336 × 10⁻¹⁰ amperes in SI units. It was defined based on electrostatic force rather than magnetic effects.

The statampere was developed as part of the electrostatic CGS unit system in the late 19th century. It was designed to simplify electrostatic equations by making the permittivity of free space dimensionless, though it resulted in very small numerical values for practical currents.

Statamperes are obsolete in modern applications and appear only in historical scientific literature or specialized theoretical physics contexts. They've been completely replaced by SI units in all practical and educational applications.

A milliampere (mA) is a unit of electric current equal to one thousandth of an ampere. It represents small current levels typically found in electronic circuits, sensors, and low-power devices.

The milliampere became important with the development of electronics and precision electrical measurements in the early 20th century. It provided a convenient scale for measuring currents in radio circuits, early computers, and electronic instruments where currents were much smaller than those in power applications.

Milliamperes are extensively used in electronics, medical devices, sensors, and low-power circuits. They're standard for measuring current consumption in smartphones, LED circuits, biomedical sensors, and electronic control systems. Most electronic specifications use milliamperes.
