Is there any way to convert binary to hex, decimal to binary, etc, using a manual calculator?

By this I mean, do manual calculators have a special mode or setting that allows you to do this? I have an exam tomorrow where there's gonna be number conversion and etc. It's on the computers, and I know you can convert this easily with the Windows calculator, but my teacher has full control over the computers and has locked certain applications such as the on-screen calculator. By the way, if it helps to determine the answer, I have a fx-300MS CASIO calculator. I can do the conversions the good old way easily through paper and pencil, but I'm honestly too lazy and I wanna make things easier for me on the exam.
