Amperes to milliamps
Type a value in A to get it in mA instantly.
100,000mA
That's 3.1× as much current as a home EV charger, while a car starter motor is 2× more. At 230 V that carries about 23,000 watts.
Convert the other way: mA to A
What it means
What draws that much?
Household power is shown at 230 V. At 120 V the same current delivers about half the watts.
The math
How to convert A to mA
To convert amperes to milliamps, multiply by 1,000.
Example: 100 A × 1,000 = 100,000 mA.
In the other direction, 1 mA = 0.001 A.

About these units
Amperes (A)
The SI unit of current: one coulomb of charge per second. Household circuits carry 10 to 32 A.
Milliamps (mA)
A thousandth of an amp. LEDs, sensors and phone charging are measured in milliamps.
