There are approximately 454 grams in 16 ounces of dry rice noodles.
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.
About 4oz of dry pasta per person times 26 people is total ounce amount, then divide by 16 ounces will give you pound weight

To measure 5 oz of spaghetti from a 1 lb package, you can use a kitchen scale to weigh out the spaghetti. First, weigh the whole 1 lb package, then remove the excess spaghetti until you have 5 oz remaining. Alternatively, you can estimate by dividing the package by 16 (since there are 16 oz in a lb) and then taking out the appropriate fraction to reach 5 oz.
16 ounces equates to 453.592 grams.
12 to 16 ounces is approximately 340 to 454 grams.
A standard single-layer DVD typically weighs around 16 grams.
80 grams of water is 16 teaspoons.
according to "http://www.ilovepasta.org/faqs.html#Q10", 8 oz. of uncooked spaghetti makes about 4 cups, so 1 pound would make about 8 cups
That is 454 grams.
