It depends on the potato. Red potatoes are smaller than Russets and so forth.
For a standard white or Russet potato, it would be about 46-47 medium whole potatoes OR 15.5 pounds.
1 lb. = 3 medium = 2 1/4 c. peeled and diced.
That is approximately 2.2 cups of potatoes
One pound of potatoes yields about three cups of peeled & sliced potatoes.
One pound of potatoes yields about three cups of peeled & sliced potatoes.
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
That would be 2.5 pounds.
There are approximately 5 cups of instant mashed potatoes in 1 lb. Instant mashed potatoes are less dense than fresh potatoes, so they take up more volume per pound. This means that 1 lb of instant mashed potatoes will yield more cups compared to 1 lb of fresh potatoes.
That is about 4 cups
{| |- | 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. |}
The number of sweet potatoes needed to make 4 cups of cubed sweet potatoes can vary based on the size of the potatoes. On average, one medium sweet potato yields about 1 to 1.5 cups when cubed. Therefore, you would typically need about 3 to 4 medium sweet potatoes to get 4 cups of cubed sweet potatoes.
If you mashed it, it would be 2 cups.
Three medium potatoes equal about 1 pound. One pound of potatoes will yield 3 cups peeled and sliced; 2 1/4 cups peeled and diced; 2 cups mashed; or 2 cups of french fries. (Answer found on North Carolina Potato Association website)
