How to convert amps to milliamps

How to convert electric current from amps (A) to milliamps (mA).

amps to milliamps calculation formula

The current I in milliamps (mA) is equal to the current I in amps (A) times 1000 milliamps per amp:

I(mA) = I(A) × 1000mA/A

 

So milliamps are equal to amps times 1000 milliamps per amp:

milliamp = amp × 1000

or

mA = A × 1000

Example 1

Convert current of 5 amps to milliamps:

The current I in milliamps (mA) is equal to 5 amps (A) times 1000mA/A:

I(mA) = 5A × 1000mA/A = 5000mA

Example 2

Convert current of 7 amps to milliamps:

The current I in milliamps (mA) is equal to 7 amps (A) times 1000mA/A:

I(mA) = 7A × 1000mA/A = 7000mA

Example 3

Convert current of 15 amps to milliamps:

The current I in milliamps (mA) is equal to 15 amps (A) times 1000mA/A:

I(mA) = 15A × 1000mA/A = 15000mA

Example 4

Convert current of 25 amps to milliamps:

The current I in milliamps (mA) is equal to 25 amps (A) times 1000mA/A:

I(mA) = 25A × 1000mA/A = 25000mA

Example 5

Convert current of 50 amps to milliamps:

The current I in milliamps (mA) is equal to 50 amps (A) times 1000mA/A:

I(mA) = 50A × 1000mA/A = 50000mA

How many amps is a mA?

Definition: A milliampere (symbol: mA) is a submultiple of the ampere, the SI base unit of electric current. It is defined as one thousandth of an ampere.

What is the difference between AMP and mA?

One milliamp is equal to one thousandth of an amp. For example, 0.1 amps is equal to 100 milliamps and 0.01 amps is equal to 10 milliamps. While the term "milliamp" is used in spoken communication, it is abbreviated as MA in writing.
