I need help

I have some WETH in my Coinbase wallet I am trying to turn back into ETH. I’ve tried everything and I can’t seem to find a way to do it. I’ve tried getting it to Metamask but when I go to send it, it says I need ETH to pay the miner’s fee, which I have ETH in my Coinbase wallet but it still won’t work. Can someone please let me know a way I can do this?
