How much would it cost to replace all Ethereum hash rate?

My maths:

– Today hash rate, 930 TH/s – Source https://www.coinwarz.com/mining/ethereum/hashrate-chart

– Mining rig of 100 TH/s, $14k – Source https://www.amazon.co.uk/AntMiner-Bitmain-S19-Bitcoin-Miner/dp/B08BPFYKMW

So with $140k we would replace the entire network…

What am I getting wrong here?

​

Edit: Thanks for the answers. I'm using BTC miners, not ETH miners.
