Etherum gas fees explanation

Hi guys, new to crypto here so dont blame me for not understanding too much

I recently learned about etherum gas fees but i cant wrap my mind around it I actually mine from nanopool and from what i undestood i need to pay this fees 2 time 1) from nanopool to wallet 2) from wallet to binance

Main point i dont get how i should calculate the actual fees. I can see the gas price is like 298 gwei (that is the measurment right?) Now, how can i calculate how much will cost to trasfer 0.05 eth? Because i saw those day the price went crazy high reading about fees around 30/40 dollars

Thx for the explanation guys
