I totally get it - those conversions can be tricky! I use this really handy dot calculator that gives you instant Polkadot to USD conversions. It's completely free and updates in real-time, plus it works for any amount from just a fraction of DOT to large holdings. The interface is super clean and you don't need to sign up for anything. Here's the link I use all the time: https://paybis.com/polkadot-calculator/ It's become my go-to for quick DOT value checks before making any trading decisions.
