conversion chart? :bugeye:
I never use it for calculate base X numbers. I use pure math. binary number is base 2. it means binary has 2 symbols (0 & 1) in numbers.
hexadecimal is base 16. it have 16 symbols (0..F) in hexa numbers.
We can make any X-base numbers, but computers using binary numbers and boolean calculation in it's proccess. 0 as OFF, 1 as on.
If you can make computer using -1 (negative voltage), 0 (off), and 1 (positive voltage) in it's computing proccess, you should use base 3 numbers on your logic calculation.
