If it is a side dish, 6 -8 people could get a small serving.
only 1kg is enough for 3 peoples
an average potato may weigh 150 grams (0.33 lb) so there could be 20/25 in an 8 lb bag
To make cheesy potato casserole most recipes require about 2 pounds of potatoes to feed 8 people. If you are feeding 150 people the recipe would need to be made 19 times over and require 38 pounds of potatoes.
That is approximately 8 oz of potato.
1/8 = .125 and 3/5 = .6 Therefore 1/8 < 3/5
{| |- | 4 lbs. of white potatoes will make approximately 8 cups of cubed potatoes. On average, 1 lb. of white potatoes = 3 med. potatoes = 3 cups grated potatoes = 2 cups cubed potatoes = 1-3/4 cup mashed. |}
It depends on how big your potato is. If it is a large one then 1/2 a potato per person. If the potato is small then 1 potato per person.

One pound of of white or russet potatoes makes approximately 1 3/4 cups of mashed potatoes. Using that measurement, then five pounds of potatoes would make approximately 8 3/4 cups of mashed potatoes. Source: http://southernfood.about.com/library/info/blequivp.htm
mashed potatoes for 1 person would be about two good sized potatoes, which weigh approximately 400g. Therefore 80kg of potatoes would feed about 200 and if anyone wants second portions or there are some larger people in your party, then 100kg or 220lb of potatoes should suffice.
I have done this! Wrap your potatoes in aluminum foil and place in electric roasters. You can get about 30-35 potatoes in each roaster. I started them at 400 at 7:00 am. About 8:30, we took the ones on the outside and place the inside ones on the outside. and put the outside ones on the inside. We then kept watching them and switching some around. They were done by 11:00 a.m.
