How to Convert Watts (W) to Milliamperes (mA)

Converting Watts (W) to Milliamperes (mA) requires knowing the voltage (V) of the circuit. The formula is:

The current I in milliamperes (mA) is equal to the power P in watts (W) divided by the voltage V in volts (V) and then multiplied by 1,000:

I(mA) = (P(W) / V(V)) × 1,000

If you have a power measurement of 10 W and the voltage is 5 V, the calculation would be:

I(mA) = (10 W / 5 V) × 1,000 = 2,000 mA

Watts (W) represent the rate of energy transfer or conversion, indicating how much energy is used per unit of time.

Voltage (V) is the electrical potential difference that drives the current through a circuit.

Milliamperes (mA) represent the flow of electric charge, measuring the current in a circuit.

Always ensure you know the voltage when calculating current to get accurate results!
