Unit Description
Milliampere (mA)
Definition
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.
History
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.
Current Use
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.
Ampere (A)
Definition
An ampere (A) is the SI base unit of electric current, defined as the flow of one coulomb of electric charge per second. It represents the fundamental measure of electrical current flow in a conductor.
History
The ampere was named after French physicist André-Marie Ampère in 1881. Originally defined in terms of the force between current-carrying conductors, it was redefined in 2019 based on the elementary charge, providing a more fundamental and precise definition tied to quantum mechanics.
Current Use
Amperes are universally used for measuring electrical current in all applications, from household electronics to industrial systems. They're essential for electrical safety, circuit design, power calculations, and are found on every electrical device rating, fuse, and circuit breaker.

- Conversion Formula: A = mA ÷ 1,000
- Calculation: 1 mA ÷ 1,000 = 0.001 A
Convert 10 Milliampere to Ampere
- Conversion Factor: 1 mA = 0.001 A
- Conversion Formula: A = mA ÷ 1,000
- Calculation: 10 mA ÷ 1,000 = 0.01 A
Convert 100 Milliampere to Ampere
- Conversion Factor: 1 mA = 0.001 A
- Conversion Formula: A = mA ÷ 1,000
- Calculation: 100 mA ÷ 1,000 = 0.1 A
Convert 1,000 Milliampere to Ampere
- Conversion Factor: 1 mA = 0.001 A
- Conversion Formula: A = mA ÷ 1,000
- Calculation: 1,000 mA ÷ 1,000 = 1 A
