Q:

How much is 1 gas in ether?

On Etherscan the daily GasUsed chart shows current usage of 10-15 bill.  How do I convert this correctly to ether (ETH)?.  

A:

There's no such thing as '1 gas'. You can't convert gas to ether because those are two different things. Gas is a measure of the computational power needed to execute the transaction. You're probably asking about gas cost which is gas * gas price and is usually measured in Gwei. 1 eth = 1e9 Gwei.
