This online converter allows you to easily convert between ampere (a) and milliampere (ma), providing instant results with high precision.
Ampere (A)
Definition: The ampere (symbol: A) is the SI base unit of electric current, defined as the constant current that, if maintained in two straight parallel conductors of infinite length and negligible circular cross-section placed one meter apart in a vacuum, would produce a force equal to 2×10⁻⁷ newtons per meter of length.
History: Named after André-Marie Ampère, one of the founders of electrodynamics. Originally defined in 1881 through electrolysis, it was redefined in 1948 based on the force between wires, and again in 2019 as part of the SI redefinition using the elementary charge.
Current use: Fundamental to all electrical measurements, used in circuit design, power systems, and electronics. The standard unit for measuring current flow in everything from household appliances to industrial machinery.
Milliampere (mA)
Definition: A milliampere (symbol: mA) is one thousandth of an ampere (10⁻³ A). This unit is practical for measuring smaller currents typical in electronic circuits.
History: Derived from the ampere with the metric prefix 'milli-' (thousandth). Gained importance with the development of sensitive electronic devices in the 20th century.
Current use: Commonly used to measure currents in consumer electronics (smartphones draw 100-500mA), sensor circuits, and medical devices (EEG machines typically use mA ranges).
