What is a Current Converter?
A current converter is a simple tool that helps you change electrical current from one unit to another. Current is the flow of electric charge through a wire or circuit. Think of it like water flowing through a pipe - the current tells us how much electricity is moving.
Our ampere converter makes it easy to switch between different current units. You might need to convert amperes to milliamps when working with small electronics. Or you might convert microamps to amperes when checking sensor readings. This electrical current calculator does all the math for you.
The amp converter works with many units like amperes, milliamperes, microamperes, kiloamperes, and more. Each unit measures the same thing - electrical current - but in different sizes. It's like measuring distance in meters, centimeters, or kilometers.

A small LED uses about 20 milliamperes of current.
20 mA = 0.02 A
Phone Charger
A phone charger typically uses 1-2 amperes.
1.5 A = 1500 mA
Car Battery
Starting a car can use 200-400 amperes.
300 A = 0.3 kA
Microchip
A tiny microchip uses microamperes of current.
50 μA = 0.00005 A
House Fuse
A typical house fuse is rated for 15-20 amperes.
15 A = 15000 mA
Watch Battery
A digital watch uses very little current.
10 μA = 0.01 mA
Simple Current Facts
What is Current?
Current = Electric charge ÷ Time
Think of it like:
• Water flowing through a pipe
• More current = more electricity flowing
• Measured in amperes (amps)
Easy Conversions
1 ampere = 1000 milliamperes
1 milliampere = 1000 microamperes
1 kiloampere = 1000 amperes
Bigger units have fewer numbers
Smaller units have more numbers

Frequently Asked Questions
What is the difference between amperes and milliamperes?
Amperes (A) and milliamperes (mA) both measure electrical current. One ampere equals 1000 milliamperes. Milliamperes are used for smaller currents, like in electronics. Amperes are used for bigger currents, like in house wiring.
How do I convert amperes to milliamps?
To convert amperes to milliamps, multiply by 1000. For example: 2 amperes × 1000 = 2000 milliamperes. Our ampere converter does this math automatically for you.
When would I use microamperes?
Microamperes (μA) are used for very small currents. You see them in sensors, medical devices, and tiny electronic parts. One microampere is one millionth of an ampere.
Is this current converter accurate?
Yes, our electrical current calculator uses exact conversion factors. The math is based on standard electrical units. You can trust the results for your projects and calculations.
What are kiloamperes used for?
Kiloamperes (kA) are used for very large currents. You find them in power plants, large motors, and electrical transmission lines. One kiloampere equals 1000 amperes.
Can I use this for DC and AC current?
Yes, current units are the same for both DC (direct current) and AC (alternating current). The ampere converter works for any type of electrical current measurement.
