1000
1000*0.001= 1 watt
This would depend on the voltage. There is a formula you use to figure wattage which is amps X volts = watts. Since a milliamp is 1/1,000th of an amp, then if the voltage is, say the standard 120...
Watts are amps times volts, so w/o the volts there's no way of telling.
1 mega-watt = 1,000,000 watts 1000 x 1,000,000 = 1,000,000,000 or one billion watts 1000 mega-watts also = 1 giga-watts
