How do you track the gas fees for a transaction?

Hi!, I haven't used ethereum for a while because of the gas fees, but now I am forced to (freakin Coinbase sent MATIC to my Metamask through ethereum and not through poligon. ).

I've seen that Coinmarketcap.com has a gas fee tracker, but it's marked at 35 Gwei right now, which equals to 0.00011887295 USD, and it's obviously incorrect. Maybe I have a misconception and you have to pay that amount of Gwei a bunch of times for the transaction to go through…

​

So, how can I track the price of gas fees for a transaction?
