power measure

Hi!

I need to measure the power of some devices. I'm thinking to made a
digital ampermeter, since I already know the voltage (220 V), I only
need to measure the current to get the power (according to the formula
P = I x V), right?
Does anybody have a schematic or a link to a digital ampermeter?
Or have another idea to measure the power of a device?
This must be digitally made, since this value will be used in a PIC
controller.

Thanks in advance.
