I am using **etherscan** api to get balance using the address. But I am getting a response in wei. After some research, I got some WEI to eth converter methods.  

[WEI to eth](https://github.com/Nethereum/Nethereum/blob/master/src/Nethereum.Util/UnitConversion.cs)  

But I don't know which method will suitable for me and how I will convert this in Objective -c? 

Thanks in advance.
