Computer programmers and system engineers often need to convert hexadecimal numbers such as FF to decimal numbers (255) and vice-versa, but don't want to open up the Windows XP calculator tool?

The Sysinternals website, part of Microsoft TechNet, offers a free DOS hexadecimal to decimal conversion program called hex2dec. Simply download a zip file, unzip the executable inside hex2dec.zip to your main Windows directory, and you can convert numbers on the command line like so:

Convert hexadecimal 77 to decimal

C:\>hex2dec 0x77
