mA or current is only an element of Watts. Watts= voltage x current (amps). So multiply 0.650 (650mA) by the supply voltage to get the wattage. e.g. if its a 12 volt supply you get 12 x 0.650 = 7.8 watts
A small battery AM or FM radio uses as little as 3 v at 10 mA, that is 0.03 Watts. A typical DAB radio might used 6 v at 250 mA, which is 1.5 Watts, or 40-50 times as much.
This question cannot be answered without knowing the voltage. Watts=Volts x Amps In the United States mains voltage (what you get in your house) is 120 Volts, so 120 x 400 = 48,000 Watts In Europe mains voltage is 230 Volts, so 230 x 400 = 92,000 Watts
A digital clock doesn't have watts it consumes watts. The wattage consumed by the clock is in the neighborhood of W = A x V, W = 400 ma (.400) x 9 = 3.6 watts.
About 298,400 watts.

mA stands for milliAmpere. milli- means 1/1000th.So 1mA = 0.001 A400 mA = 0.400 A

It depends on the supply voltage watts = current in amps times the supply voltage
