Is this what you're looking for? It's a PDF chart that lists the 1-stop increments for aperture, shutter speed, and ISO.
If you have a smart phone, there are various apps for exposure or even to use your phone's camera as a light meter although I don't use them so can't recommend any personally.
Go to phototraces.com and scroll down. You will find "cheat sheets" for ISO, f-stop, and shutter speed.
