Converting milliamps to amps is relatively easy. You can do this manually or get a quick milliamp to amps conversion using our calculator below!

What Are Milliamps and Amps?

Milliamperes (mA) and amperes (A) are units of electric current. Electric current is the flow of electric charge in a circuit. You can measure the flow of charge in terms of the quantity of electric charge passing through a certain point in a unit of time. 

One amp is the base unit of electric current. It is defined as the amount of electric current that flows through a conductor when one Coulomb of electric charge transfers through it in one second. 

On the other hand, a milliamp is 1/1000th of an amp. It is a smaller unit of electric current. A milliamp is typically used to measure small electric currents in devices like batteries and sensors. 

How to Convert Milliamps to Amps

To convert milliamperes (mA) to amperes (A), you can use the following conversion formula:

A = mA ÷ 1000

For example

• Imagine you have a small LED light that requires 20 milliamperes (mA) of current to operate. To find out how many amperes this is, you can convert the milliamperes to amperes by dividing the milliamperes by 1000. 

So, 20 mA ÷ 1000 = 0.02 A. This means the LED light requires 0.02 amperes to operate.

• If you have an electronic device that requires 500 milliamperes (mA) of current to function, your milliamps to amps calculation will look like this:

500 mA ÷ 1000 = 0.5 A. 

So, the electronic device requires 0.5 amperes to function.

Reasons to Convert Milliamps to Amps

Convenience: Converting milliamps to amps makes measuring smaller electrical currents easier.

Battery Life: The discharge rate of batteries is often specified in milliamperes. Converting to amps and then to kilowatts can give you an idea of how quickly a battery will discharge under a given load.

Data Logging and Monitoring: When logging or monitoring electrical signals, it may be necessary to convert between milliamperes and amperes in order to get an accurate representation of the signal.
