I am not sure whether we can directly compare 1 oz. of gold with 1 BTC, because the units are different. Why not 1 kg of gold vs 1 BTC? The only perfect comparison I could think about it between the market cap of gold, and that of BTC. And it looks like BTC is a long way behind gold. But the good news is that Bitcoin is catching up pretty fast.

What about this?

January 2017:  Market cap of gold = 400x that of BTC
January 2021: Market cap of gold = 17x that of BTC
