Amperes to Milliamperes

Convert amperes (A) to milliamperes (mA) with formulas, examples, and conversion tables.

Amperes (A)

Milliamperes (mA)

1 A = 1000 mA

Full precision:1000 mA

Step-by-Step Solution

To convert 1 amperes to milliamperes, we multiply by 1000 because one ampere equals exactly 1000 milliamperes.

1 ampere = 1000 milliamperes

Since each ampere contains 1000 milliamperes, we multiply our value by this factor:

1 × 1000 = 1000 milliamperes

So 1 amperes = 1000 milliamperes.

✓Quick check: 1000 ÷ 1000 = 1 amperes

How to Convert Amperes to Milliamperes

To convert amperes to milliamperes, multiply the value by 1000.

Milliamperes = Amperes × 1000

1 ampere = 1000 milliamperes

Tip: To convert milliamperes back to amperes, divide by 1000.

Example 1: 1 A = 1000 mA
1 × 1000 = 1000

Example 2: 5 A = 5000 mA
5 × 1000 = 5000

Example 3: 10 A = 10000 mA
10 × 1000 = 10000
