How to Change Milliamperes (mA) to Amperes (A)

Amperes (A) are the standard unit used to measure electric current worldwide. We typically use a smaller unit in electronics called the milliampere (mA). A lot of circuits, batteries, and devices show current in mA.

You should change milliamperes into amperes to work with these numbers. The technique is relatively easy once you know how the two units are related.

Conversion Formula

Amperes (A) = Milliamperes (mA) ÷ 1000

Or simply:

• 1 A = 1,000 mA

Examples

Example 1: Change 3000 mA to A

• 3000÷1000=33000 \div 1000 = 33000÷1000=3

• ✅ Answer: 3000 mA = 3 A

Example 2: Change 75 mA to A

• 75÷1000=0.07575 \div 1000 = 0.07575÷1000=0.075

• ✅ Answer: 75 mA = 0.075 A
