WATTS

The poor watt is often misunderstood. Watts are basically just a measure of how much power a device uses, or can supply, when turned on. A watt is a watt - there is no such thing as "watts per hour", or "watts per day". If something uses 100 watts, that is simply the voltage times the amps. If it draws 10 amps at 12 volts, or 1 amp at 120 volts, it is still 120 watts. A watt is defined as one Joule per second, so saying watts per hour is like saying "miles per hour per day".

WATT-HOURS

A watt-hour (or kilowatt hour, kWh) is simply how many watts times how many hours that is used for. This is what most people mean when they say "watts per day". If a light uses 100 watts, and it is on for 9 hours, that is 900 watt-hours. If a microwave uses 1500 watts, and runs for 10 minutes, that is 1/6th of an hour x 1500, or 250 WH. When you buy power from your friendly utility (look at your last bill), they sell it to you at so much per kWh. A kWh is a "kilowatt-hour", or 1000 watts for one hour (or 1 watt for 1000 hours).
