I am trying to convert pounds to cups. If I have 2 lbs of potatoes, how many cups is that?
You can't convert pounds to cups. They are 2 different systems of measuring. Pounds measure weight and cups measure volume.
Consider having 2 pounds of potatoes and 2 pounds of marshmallows. You would have considerably more cups of marshmallows than you would of potatoes.
Ditto what 'carolb' said below. This site says one pound of potatoes is approx 2 cups cooked/mashed. So 2 pounds of spuds would be 4 cups. http://www.barryfarm.com/How_tos/how_many_cups_in_a_pound_of.htm
Use that as a starting point. I would think most potato recipes would be somewhat forgiving, not like baking cakes, etc. where exact measurements count.
This one differs a bit:
> How many potatoes are in a pound?
Three medium potatoes equal about 1 pound.
ONE pound of potatoes will yield 3 cups peeled & sliced;
2 1/4 cups peeled and diced;
2 cups mashed; or
2 cups of french fries.
You can convert somethings to cups easily, like sugar or flour or rice, but you will have to cook up those potatoes, drain, mash down and measure. Then you will know. Also different potatoes mash up differently.
Gold potatoes probably weigh more than fluffier potatoes like baking potatoes.
Hmm...a pint's a pound the world around. Two cups in a pint, So 2 pounds of potatoes is approximately 4 cups.
Buy a kitchen scale. I bought a cheap one years ago and it's the best way to figure this out.
