    When an instrument/device gives you a power rating, example: 12-24 VDC; 180 MA. Then when you calculate the wattage based on your devices consumption, is it watts per hour, day..? Im sure the ratings that are given are based on a time, but I'm not sure what that is.

    In simple terms watts is a measure of power. A 60W light bulb shines brighter than a 40W bulb.
    What you are thinking of is energy. If you run a 60W light bulb for 3 hours, you will be consuming 180Wh of energy.
