How do I say "a loaf of bread"? According to Google translate it is 一个面包, but that doesn't sound right.

How do I say "A loaf of bread"?

UPDATE:

This is what I mean by a "loaf" of bread. Not just a bun.
It depends a little bit on the type of bread.

For a long bread 条 is used. For a slice of bread 片 is used. 块 can also be used for a slice, but is also used for buns, a piece of bread or a complete bread.
