Converting eth_getBalance response into ETH

To convert the hex string response, measured in Wei to a decimal value measured in ETH we need to complete two steps:

Convert the hex response into decimal (Wei).
Convert the Wei decimal into ETH decimal (10^18 wei = 1 eth).

Depending on what library or language you are using, there are several options here.

# conversion from hex string to decimal
dec = int("hex strong response",16)

# conversion from Wei to to ETH
ethBalance = dec*(10**18)Parameters
