        This chart was designed for simplistic "Digital Key Entry" but still allowing for various power equivalents.  For example 1.:  Digital Key Entry:  333 @ PL-9 (Power Level 9) will bring a 2 cup container of water & 2 scoops of coffee to a short boil with a 800 watt microwave. (Reduce time &/or PL with 1000 watt+ microwave ovens.).  For example #2.:  Digital Key Entry:  366 @ PL-8 will bring a 2 cup container of water & 2 tea bags to about 175ยบ F very nicely with a 800 watt microwave.   CAUTION:  Trying to boil water in a microwave can cause "super heating" and a non boiled "look"; yet when touched or moved can release a sudden, violent steam-out of scalding water.
       Because Microwave power can only be full "on" or totally "off" the only way the manufacturers can regulate power is by regulating the effective full "on" cooking time.  The numbers represent percentages of full power for example the #8 is 80% of full power so that the effective full "on" cooking time over 30 seconds would be  0.8 x 30 = 24 seconds "on" and "off" for 6 seconds.  For a minute at 80% it would cook: 24 sec "on" - 6 sec. off, 24 sec on - 6 sec. off for an effective cooking time total of 48 seconds "on".  [BTW the owners manual didn't have this info. in it.  I had to figure it out for myself.]
        One of my favorite items is baked potatoes and I've learned that  8 oz. at 8 minutes at PL-6 bakes one just right.
