For a live VTHO to USD conversion, try https://paybis.com/vethor-token-calculator/ just enter any amount and it instantly shows the dollar value, updated in real time. It handles all those decimals perfectly, even for small amounts. You can also reverse it to see how much VTHO you'd get for a specific USD amount. The page includes a 7day price history and a profit calculator if you want to track your staking earnings over time. No account needed, just clean numbers.
