Watts to milliamps
Type a value in W to get it in mA instantly.
833.3mA
That's 1.54× as powerful as a laptop, while a microwave is 10× more powerful. At 120 V it draws 0.8333 A.
Convert the other way: mA to W
What it means
How much power is that?
For DC and for resistive AC loads (heaters, kettles, lamps). Motors and power supplies have a power factor below 1 and draw more amps for the same watts.
The math
How to convert W to mA
amps = watts ÷ volts; watts = amps × volts (DC, or AC with a power factor of 1).
Example: 100 W = 833.333 mA.
Amps on this page are at 120 V (US, Canada). Pick another voltage above.
