I was dealing with the same thing until I found a dedicated page for exact amounts like this. There's a calculator that shows the live value for 0.47 SOL in USD, updated in real time. It's at https://paybis.com/sol-to-usd/0.47/ and it shows the current rate, a 7-day price history so you can see the trend, and even a profit calculator. Right now, 0.47 SOL is around $40.60 depending on the exact rate. Much easier than doing manual math every time.
