How do I convert amperes to milliamperes?
To convert amperes (A) to milliamperes (mA), select 'Amperes' as your 'Convert From' unit and 'milliamperes' as your 'Convert To' unit. Enter the value in Amperes, and the converter will instantly show you the equivalent in milliamperes. (1 Ampere = 1000 milliamperes).
What are milliamperes (mA) and microamperes (µA) typically used for?
Milliamperes (mA) and microamperes (µA) are commonly used in electronics to measure smaller currents found in circuits for devices like phones, computers, and sensors. Milliamps are often used for battery capacity ratings (e.g., mAh - milliamp-hours).
What are kiloamperes (kA) and megaamperes (MA) used for?
Kiloamperes (kA) and Megaamperes (MA) are used to measure very large currents typically found in heavy electrical engineering applications, such as power transmission lines, industrial machinery, welding equipment, or in the analysis of fault currents.

What is Electric Current?
Electric current is the flow of electric charge through a material or space. It is measured as the rate of flow of charge, and its standard unit in the International System of Units (SI) is the Ampere (A). Understanding electric current and being able to convert between its different units is fundamental in electronics, electrical engineering, and physics.
The Ampere and its Metric Subunits and Multiples
The Ampere (A) is the base unit of electric current. For measuring smaller currents, metric prefixes are used: milliampere (mA) = 10^-3 A, microampere (µA) = 10^-6 A, nanoampere (nA) = 10^-9 A, and picoampere (pA) = 10^-12 A. For very large currents, kiloampere (kA) = 10^3 A, and megaampere (MA) = 10^6 A are used. Our converter handles conversions across this wide range.
Why Accurate Current Conversion is Important
Accurate electric current conversion is critical in many electrical and electronic applications. Engineers need precise current values for circuit design, component selection, and power calculations (e.g., using Ohm's Law or power formulas). Incorrect conversions can lead to component failure, safety hazards, or inefficient system design. Using a reliable converter ensures precision.
Applications in Electronics vs. Electrical Power Systems
The scale of current measurements differs significantly between fields. Electronics typically deals with smaller currents measured in milliamperes (mA) or microamperes (µA). Electrical power systems, on the other hand, involve much larger currents measured in Amperes (A) or even kiloamperes (kA) and megaamperes (MA) in high-voltage transmission. Our converter bridges the gap between these different scales.
Converting Between Different Current Units
Converting between current units primarily involves multiplying or dividing by powers of 1000, based on the metric prefixes. For example, converting Amperes to milliamperes means multiplying by 1000. Converting microamperes to Amperes means dividing by 1,000,000. Our online tool automates these calculations, providing instant results across the entire range of supported units.
Relation to Other Electrical Quantities (Briefly)
Electric current (Amperes) is related to Voltage (Volts), Resistance (Ohms), and Power (Watts) through fundamental laws like Ohm's Law (Voltage = Current x Resistance) and the power formula (Power = Voltage x Current). While our tool focuses solely on current unit conversion, understanding these relationships highlights why accurate current measurement and conversion are vital in electrical calculations.
