Convert Milliamps to Amps
Type the number of milliamperes that you wish to convert to amperes.
How to Convert Milliamperes to Amperes
The milliampere and ampere are both units of electric current. By definition, 1 milliampere equals exactly 1000000 amperes. This means to convert milliamperes to amperes, you multiply by 1000000.
Formula
Step-by-Step Example
Convert 5 mA to amperes:
We need to convert milliamperes to amperes
Since 1 mA = 1000000 A, multiply by 1000000
5 × 1000000 = 5000000
5 mA = 5000000 A

About These Units
Milliampere (mA)
A milliampere (mA) equals 0.001 amperes or 1,000 microamperes. Common for electronic devices: LED current 10-20 mA, USB 2.0 charging 500 mA, USB 3.0 up to 900 mA, fast charging 1,500-3,000 mA. Dangerous current through human body starts around 10-20 mA.
Ampere (A)
The ampere (A or amp) is the SI base unit of electric current, defined by the flow of elementary charges per second. Named after physicist André-Marie Ampère. Common currents: LED 20 mA, USB 0.5-3 A, household outlet 15-20 A, electric car charger 32-80 A. Formula: I = V/R (Ohm's law).
