In what system of calculation does Etherium show the balance?

Question

Cryptocurrency

When working through geth, requesting the balance of a certain wallet, a response like this is returned to the console:

{"jsonrpc":"2.0","id":67,"result":"0xdab5a87251800"}

in what system of calculation is the result parameter displayed? And how, for example, in php to translate this value into a decimal system?

ps: in decimal this number looks like this: 0.00384758. I looked at etherscan
