Quick Decimal, Hex, Binary, Octal Conversion on Windows

Sometimes you just need a quick and dirty way to convert between number systems (decimal, hex, octal, binary). The built in Windows calculator will actually do this for you. Simply start the calculator and under "View" choose "Programmer".

This should switch to the Programmer calculator view. Set the mode to whatever number system you are converting from - it should default to Decimal, and enter the number.

From here you just select the number system you want to convert to.

The number auto updates to the new number system. Done, quick and easy.
