How much is $100 in grams?

Excuse me, I have a question that might sound a bit odd, but I'm really curious. You know, when we talk about money, we often use terms like dollars or euros. But what if we wanted to measure it in grams? I mean, how much would $100 actually weigh if we could weigh it like we do with other substances? Is there a way to convert currency to grams? Or is this just a crazy idea that doesn't make any sense? I'm just trying to wrap my head around this concept. Could you help me understand?
