About 100,000 light-years in diameter. (If you want to convert that to kilometers, multiply by 9.5 x 1012.)

how much miles is the milky way?

Your question is not clear. If you are asking how far away is the Milky Way, that's zero mm. Why? Because our solar system is in the Milky Way. We, you and I, are already living in the Milky Way. If you are asking how big is the Milky Way, it's roughly 100,000 light years in diameter. Our galaxy is like a big spiral; so the diameter is a good measure for its size. 1 light year is about 6 trillion miles = 6E12. So in miles our Milky Way is D = 6E12*10E4 = 60E16 miles in diameter. In case so-called scientific numbers are not your thing, that's 60 with sixteen zeros following it or 600,000,000,000,000,000 miles. If you plan on traveling that far, pack a lunch.
