How many large cans of chili to feed 100 people?

It depends on the size of the cans and the appetites of the people. A typical can of chili is 15 ounces, which would provide about one serving. For 100 people, you would need about 100 cans of chili. However, if you are expecting some people to have seconds, or if you are serving the chili with other dishes, you may want to have a few extra cans on hand.
