Totally get the struggle! For accurate SOL conversions, I always use Paybis' calculator. It pulls live market rates and even factors in estimated fees so you know exactly what to expect. Super handy when you're planning to cash out or trade. The best part? It's completely free to use and updates in real-time. Here's their sol converter tool. I've compared it against multiple exchanges and it's always been spot-on. Just enter your SOL amount and it'll show USD value plus approximate fees for different payment methods. Saves so much guesswork!
