How much is 1 billion?

Excuse me, could you please clarify something for me? I'm a bit confused about the value of a large number. Specifically, how much exactly is 1 billion? I know it's a huge number, but I'm having trouble wrapping my head around its true scale. Could you perhaps put it into a more relatable context or give me an example of something that costs or is worth 1 billion? I'd really appreciate your help in understanding this.
