well bascially say you have a number 27 in octal. For each bit in octal, it is equal to 3 bits in Binary. So 2 = ??? and 7 = ???. 2 is 010 in binary and 7 is 111 so 27 in octal = 010111 in binary.

For the other way round, say you have an 8 bit binary number 010011101. Split the number into 3 smaller numbers so 010 011 101. then work out each numbers binary value so 010 = 2, 011=3 and 101=5 so in octal 010011101 = 235 in Octal.

Well, that's what base 8 and 2 are :rolleyes:

what if the binary counterpart of a decimal repeats itself. e.g. i'm trying to convert 5.3 to binary but the bit after the decimal points keeps repeating itself like 101.010011001100110011...
