How Many Calories In A Bag Of Chips?

That depends what kind of chips you mean. People in the UK and the US
sometimes mean different things. There are two types of potato chips.

• There are hot potato chips, also called fries, which are made from
  thick or thin strips of potato (if they are very thin strips they are
  often called french fries).
• There are also (usually) cold potato chips (snacks) also called a
  potato crisps (sometimes called game chips when served with roast game
  birds), which are made from thin slices of potato.

For more information about both type of chips, and to see photographs
of each (so you can be sure), please see the Wikipedia page links,
