Ampere to milliampere Conversion

1 ampere (A) is equal to 1000 milliampere (mA).

1 A = 1000 mA

1 mA = 0.001 A

Formula

To convert a electric current from ampere (A) to milliampere (mA), multiply the electric current in ampere by 1000

e_(mA) = e_(A) × 1000

Examples:

Convert 100 ampere to milliampere:

e_(mA) = 100A × 1000 = 100000 mA

Frequently asked questions

How do I convert ampere to milliampere?

Multiply the value in ampere by 1000 to get the result in milliampere. For example, 5 A × 1000 = 5000 mA.

How many milliampere are in 1 ampere?

1 ampere (A) is equal to 1000 milliampere (mA).

How do I convert milliampere back to ampere?

Use the inverse operation: divide the value in milliampere by 1000 to get the result in ampere.

How accurate is the ampere to milliampere conversion?

The converter multiplies by the conversion factor 1000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
