Check the manufacturer plate label on your microwave. It may be written like this- KW usually beside the Manufacturer model number.
You could also do a little calculation by checking the voltage and ampage readings. multiply them is going to give you wattage.
SOURCE: microwave frequency
The frequency has to do directly with the the wave a microwave oven omitts. Frequency is a measure of the number of occurrences of a repeating event per unit time. Usually microwaves run at a frequency of 2.54 Ghz, a wave length of 12.34 CM.
SOURCE: How can I find out what wattage my Emerson MW8778W microwave is?
I also bombed out on locating a downloadable manual but the hardcopy is available on eBay here:

The efficiency of microwave oven is ~ 65% so if you will check the back of your unit for the AC line (input power) consumed, you can easily calculate the usable 'cooking' power available.
i.e. If the label states: 115 VAC 10 Amp(eres), this would amount to 10 X 115 = 1150 X .65 = ~ 740 watts delivered to the food.
The magnetrons do age (if not fail first) and their emissions fall with progressive use so a 10 year-old oven won't still give you that ~65% but substantially less.

I still have a orginal lable on my microwave, it is a 800 watt oven.
