How do I convert the hex value from characteristic value to decimal?

Hi, I have managed to get my nrf51822 DK kit to read LDR sensor values. However the characteristic values are represented as hex on the master control panel and also on the android code sample from android studio. How can I read the characteristic values as decimals or display them as decimals?
