you know how on the pack of food packaging it will give various times dependning on the cateogry and power of the microwave, and it seems the two ratings are always paired.
i.e. you have 750W - category D, 850W - Category E (and there's a 600 and something below those).
the thing is, my microwave says on it "900W - Category D" which is slightly confusing because there are even more watts than a category E microwave, but yeh you get my drift. this confusion only has practical problems in the sense that i don't know how long to put my food on for, because i don't know whether to adjust the cooking time to a D power rating, or even slightly higher than an E one. so although i probably sound like eugene from bb6, help would be much appreciated. thanks.
