A cup and an ounce measure different things. A cup is a measure of volume, while an ounce is a measure of weight. Generally speaking, dry spaghetti (or most any dry pasta) will double in size when you cook it. I'd estimate that if you cook 2 ounces of dry spaghetti, you will get roughly one cup cooked spaghetti.
A serving size of spaghetti is considered to be 1/4 to 1/2 cup. Since you can not measure spaghetti in a measuring cup let's switch to ounces. 1/4 of a cup of dry spaghetti is 2 ounces, once cooked it measures about 4.5 ounces. So to get enough cooked spaghetti for 1 serving per person, for 20 people you need 20 about 20 ounces of dry spaghetti, or 1.25 lbs. 1.25 lbs of dry spaghetti will cook into approximately 2.8 lbs of cooked spaghetti, which is 45 ounces. 45 ounces which is roughly 5.6 cups, and 5.6 cups divided into 1/4th cup servings of cooked spaghetti gives you about 22 servings. If you feel people are going to want more than 1 serving then cook up another half pound of spaghetti to be safe.

Dry measure tends to be SLIGHTLY more than liquid measure, which in most recipes won't change things. But, if the recipe has to be increased to feed more people, then what started out as 1/8th cup can end up being 1/4 or 1/2, depending on the amounts used.
