Ampere to Milliampere

1 A = 1,000 mA

One ampere equals 1,000 milliamperes, and one milliampere equals 0.001 amperes.

Ampere to Milliampere formula

mA = A × 1000

To convert amperes to milliamperes, multiply the value by 1000. One ampere equals 1,000 milliamperes.

Step-by-step examples

Convert 1 amperes to milliamperes

  1. 1Start with the value in amperes: 1 A.
  2. 2Multiply by the conversion factor 1000.
  3. 31 × 1000 = 1,000 mA.

Result: 1 A = 1,000 mA

Convert 10 amperes to milliamperes

  1. 1Start with the value in amperes: 10 A.
  2. 2Multiply by the conversion factor 1000.
  3. 310 × 1000 = 10,000 mA.

Result: 10 A = 10,000 mA

Convert 100 amperes to milliamperes

  1. 1Start with the value in amperes: 100 A.
  2. 2Multiply by the conversion factor 1000.
  3. 3100 × 1000 = 100,000 mA.

Result: 100 A = 100,000 mA
