Milliamps to Watts Converter
How to Convert Watts (W) to Milliamperes (mA)
Watts (W) to Milliamperes (mA) conversion depends on the voltage (V) of the circuit. The basic formula is:
W to mA Calculation Formula
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)) × 1,000Example Calculation
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 mAFormulas for Conversion
1. DC Circuit
Power (W) = Current (A) × Voltage (V)2. Single-Phase AC Circuit
Power (W) = Voltage (V) × Current (A) × Power Factor (PF)3. Three-Phase AC Circuit
Line-to-Line (L-L):
Power (W) = 3 × Voltage (V) × Current (A) × PFLine-to-Neutral (L-N):
Power (W) = 3 × Voltage (V) × Current (A) × PFPower (W)
Watts (W) represent the rate of energy transfer or conversion, indicating how much energy is used per unit of time.
Voltage (V)
Voltage (V) is the electrical potential difference that drives the current through a circuit.
Current (mA)
Milliamperes (mA) represent the flow of electric charge, measuring the current in a circuit.
Pro Tip
Always ensure you know the voltage when calculating current to get accurate results!
