Convert Megaampere to Microampere

Convert megaamperes to microamperes by entering a value below.

1 MA (megaamperes) = 1e12 μA (microamperes)

How to Convert Megaamperes to Microamperes

The megaampere and microampere are both units of electric current. By definition, 1 megaampere equals exactly 1e12 microamperes. This means to convert megaamperes to microamperes, you multiply by 1e12.

Formula

microamperes = megaamperes × 1e12

Step-by-Step Example

Convert 5 MA to microamperes:

1
Convert 5 MA to microamperes

We need to convert megaamperes to microamperes

2
Apply the formula

Since 1 MA = 1e12 μA, multiply by 1e12

5 × 1e12 = 5e12

Answer

5 MA = 5e12 μA

About These Units

Megaampere (MA)

A megaampere (MA) equals 1,000,000 amperes. Found in fusion reactor plasma currents (ITER: 15 MA), lightning return strokes (peak can exceed 1 MA briefly), electromagnetic launchers, and pulsed power systems. Extreme currents creating enormous magnetic fields.

Microampere (μA)

A microampere (μA) equals 10⁻⁶ amperes or 0.001 milliamperes. Used in low-power electronics: watch batteries draw 1-2 μA, sleep mode microcontrollers 1-100 μA, pacemakers 10-25 μA, biosensors and electrochemical cells. Critical for battery life calculations.
