How many potatoes in 2.5 pounds?

It's impossible to say exactly how many potatoes are in 2.5 pounds without more information. Here's why:

* Potato size varies greatly. A tiny "new" potato could weigh an ounce, while a large russet could weigh over a pound.

* Potato shapes aren't consistent. You can't assume potatoes are perfectly round or even close to a standard shape.

What you can do:

1. Estimate based on your potatoes. Look at the potatoes you have. Are they small, medium, or large? You can use this to get a rough idea of how many might fit in 2.5 pounds.

2. Weigh your potatoes. The most accurate way to determine how many potatoes you have is to weigh them individually.

Let me know if you can provide more information about the size of the potatoes, and I can give you a better estimate.
