Convert Milliamperes to Microamperes
Convert Milliamperes (mA) to Microamperes (µA) instantly and accurately.
Conversion Formula
µA = mA × 1000
About Milliamperes
The milliampere (mA) equals 10⁻³ A, the everyday unit in consumer electronics and safety standards. Standard LEDs operate at 5-30 mA; USB 2.0 ports supply up to 500 mA; USB-C fast-charging delivers 3 000-5 000 mA. The milliampere is also the clinically important range for electric shock - ventricular fibrillation threshold is around 100 mA, and 1 mA is the threshold of perception. 1 mA = 10⁻³ A = 10³ µA.
About Microamperes
The microampere (µA) equals 10⁻⁶ A, common in low-power sensor circuits, analogue signal conditioning, and bioelectrical measurement. Surface ECG electrodes record body currents of 1-100 µA; a 1 mW signal at 5 V draws 200 µA; modern low-power microcontrollers sleep at 1-10 µA, enabling coin-cell operation for months or years. 1 µA = 10⁻³ mA = 10³ nA.
